Add abi parameter to get_abi_* calls in multilib_toolchain_setup (bug #138296)
since it is clearly necessary.  Thanks to Rickard Narstrom.

10     DESCRIPTION="Based on the ${ECLASS} eclass"
11    
12 eradicator 1.14 # has_multilib_profile:
13 eradicator 1.15 # Return true if the current profile is a multilib profile and lists more than
14     # one abi in ${MULTILIB_ABIS}. You might want to use this like
15     # 'use multilib || has_multilib_profile' until all profiles utilizing the
16     # 'multilib' use flag are removed from portage
17 eradicator 1.14
18     # is_final_abi:
19     # Return true if ${ABI} is the final abi to be installed (and thus we are
20     # on our last run through a src_* function.
21    
22     # number_abis:
23     # echo the number of ABIs we will be installing for
24    
25 eradicator 1.17 # get_install_abis:
26 eradicator 1.14 # Return a list of the ABIs we want to install for with
27     # the last one in the list being the default.
28    
29 eradicator 1.17 # get_all_abis:
30     # Return a list of the ABIs supported by this profile.
31     # the last one in the list being the default.
32    
33 eradicator 1.16 # get_all_libdirs:
34 eradicator 1.14 # Returns a list of all the libdirs used by this profile. This includes
35     # those that might not be touched by the current ebuild and always includes
36     # "lib".
37    
38     # get_libdir:
39     # Returns the libdir for the selected ABI. This is backwards compatible
40     # and simply calls get_abi_LIBDIR() on newer profiles. You should use this
41     # to determine where to install shared objects (ex: /usr/$(get_libdir))
42    
43     # get_abi_var <VAR> [<ABI>]:
44     # returns the value of ${<VAR>_<ABI>} which should be set in make.defaults
45     #
46     # get_abi_CFLAGS:
47     # get_abi_CDEFINE:
48     # get_abi_LIBDIR:
49     # Aliases for 'get_abi_var CFLAGS', etc.
50    
51     # get_ml_incdir [<include dir> [<ABI>]]
52     # include dir defaults to /usr/include
53     # ABI defaults to ${ABI} or ${DEFAULT_ABI}
54     #
55     # If a multilib include dir is associated with the passed include dir, then
56     # we return it, otherwise, we just echo back the include dir. This is
57     # neccessary when a built script greps header files rather than testing them
58     # via #include (like perl) to figure out features.
59    
60     # prep_ml_includes:
61     # Some includes (include/asm, glibc, etc) are ABI dependent. In this case,
62     # We can install them in different locations for each ABI and create a common
63     # header which includes the right one based on CDEFINE_${ABI}. If your
64     # package installs ABI-specific headers, just add 'prep_ml_includes' to the
65     # end of your src_install(). It takes a list of directories that include
66     # files are installed in (default is /usr/include if none are passed).
67     #
68     # Example:
69     # src_install() {
70     # ...
71     # prep_ml_includes /usr/qt/3/include
72     # }
73    
74     # create_ml_includes <include dir> <symbol 1>:<dir 1> [<symbol 2>:<dir 2> ...]
75     # If you need more control than prep_ml_includes can offer (like linux-headers
76     # for the asm-* dirs, then use create_ml_includes. The firs argument is the
77     # common dir. The remaining args are of the form <symbol>:<dir> where
78     # <symbol> is what is put in the #ifdef for choosing that dir.
79     #
80     # Ideas for this code came from debian's sparc-linux headers package.
81     #
82     # Example:
83     # create_ml_includes /usr/include/asm __sparc__:/usr/include/asm-sparc __sparc64__:/usr/include/asm-sparc64
84     # create_ml_includes /usr/include/asm __i386__:/usr/include/asm-i386 __x86_64__:/usr/include/asm-x86_64
85    
86 kito 1.31 # get_libname [version]
87 swegener 1.32 # returns libname with proper suffix {.so,.dylib} and optionally supplied version
88 kito 1.31 # for ELF/MACH-O shared objects
89     #
90     # Example:
91     # get_libname libfoo ${PV}
92     # Returns: libfoo.so.${PV} (ELF) || libfoo.${PV}.dylib (MACH)
