19     # This function generate linker scripts in /usr/lib for dynamic
20     # libs in /lib. This is to fix linking problems when you have
21     # the .so in /lib, and the .a in /usr/lib. What happens is that
22     # in some cases when linking dynamic, the .a in /usr/lib is used
23     # instead of the .so in /lib due to gcc/libtool tweaking ld's
24     # library search path. This cause many builds to fail.
25     # See bug #4411 for more info.
26     #
27     # To use, simply call:
28     #
29     # gen_usr_ldscript libfoo.so
30     #
31     # Note that you should in general use the unversioned name of
32     # the library, as ldconfig should usually update it correctly
33     # to point to the latest version of the library present.

106     # You do not have to specify '-p' option to patch, as it will
107     # try with -p0 to -p5 until it succeed, or fail at -p5.

109     # Above EPATCH_* variables can be used to control various defaults,

115     # Bulk Patches should preferibly have the form of:

122     # 02_sparc_another-fix.patch.bz2
123     #
