Reversing a change vapier made which broke some packages.  ABI still needs to be set for get_libdir, etc.

10 DESCRIPTION="Based on the ${ECLASS} eclass"
11
12 # has_multilib_profile:
13 # 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
18 # is_final_abi:
19 # Return true if ${ABI} is the final abi to be installed (and thus we are
20 # on our last run through a src_* function.
21
22 # number_abis:
23 # echo the number of ABIs we will be installing for
24
25 # get_install_abis:
26 # Return a list of the ABIs we want to install for with
27 # the last one in the list being the default.
28
29 # get_all_abis:
30 # Return a list of the ABIs supported by this profile.
31 # the last one in the list being the default.
32
33 # get_all_libdirs:
34 # Returns a list of all the libdirs used by this profile. This includes
35 # those that might not be touched by the current ebuild and always includes
36 # "lib".
37
38 # get_libdir:
39 # Returns the libdir for the selected ABI. This is backwards compatible
40 # and simply calls get_abi_LIBDIR() on newer profiles. You should use this
41 # to determine where to install shared objects (ex: /usr/$(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 # get_libname [version]
87 # returns libname with proper suffix {.so,.dylib} and optionally supplied version
88 # for ELF/MACH-O shared objects
89 #
90 # Example:
91 # get_libname libfoo ${PV}
92 # Returns: libfoo.so.${PV} (ELF) || libfoo.${PV}.dylib (MACH)
