Added get_all_libdirs.  Changed die to eerror/exit since die doesn't have the expected result when called from a subshell.

46 # This function generate linker scripts in /usr/lib for dynamic
47 # libs in /lib. This is to fix linking problems when you have
48 # the .so in /lib, and the .a in /usr/lib. What happens is that
49 # in some cases when linking dynamic, the .a in /usr/lib is used
50 # instead of the .so in /lib due to gcc/libtool tweaking ld's
51 # library search path. This cause many builds to fail.
52 # See bug #4411 for more info.
53 #
54 # To use, simply call:
55 #
56 # gen_usr_ldscript libfoo.so
57 #
58 # Note that you should in general use the unversioned name of
59 # the library, as ldconfig should usually update it correctly
60 # to point to the latest version of the library present.

130 # This function is for bulk patching, or in theory for just one

134 # Currently all patches should be the same format.
135 #
136 # You do not have to specify '-p' option to patch, as it will
137 # try with -p0 to -p5 until it succeed, or fail at -p5.
138 #
139 # Above EPATCH_* variables can be used to control various defaults,
140 # bug they should be left as is to ensure an ebuild can rely on
141 # them for.
142 #
143 # Patches are applied in current directory.
144 #
145 # Bulk Patches should preferibly have the form of:
146 #
147 # ??_${ARCH}_foo.${EPATCH_SUFFIX}
148 #
149 # For example:
150 #
151 # 01_all_misc-fix.patch.bz2
152 # 02_sparc_another-fix.patch.bz2
153 #
154 # This ensures that there are a set order, and you can have ARCH
155 # specific patches.
156 #
157 # If you however give an argument to epatch(), it will treat it as a
158 # single patch that need to be applied if its a file. If on the other
159 # hand its a directory, it will set EPATCH_SOURCE to this.

1026 # parameter. here is an example:
1027 # root@vapier 0 pdv_unpack # strings hldsupdatetool.bin | grep lseek
