openwrt-xburst/tools/mklibs/patches/005-readelf_fixes.patch
mirko d7f2b105ad [tools/mklibs] add missing includes ('unistd.h') for mklibs
This is needed when compiling with GCC >= 4.7.0 since it doesn't implicitly include 'unistd.h' anymore (needed e.g. for file operations in this particular case)

 - Thanks to Luka Perkov
