Many (100+) packages supported by buildroot contain old configure scripts (or build them from old versions of autotools) that are unable to determine how to link shared libraries on powerpc64 and powerpc64le. This causes that test to erroneously fail on toolchains that are not "bi-endian" (which is the case for toolchains built by buildroot), which causes configure to build static libraries instead of dynamic ones. Although these builds succeed, they tend to cause linker failures in binaries later linked against them. Because affected configure files can be discovered automatically, this patch introduces a hook (enabled only when building for powerpc64 and powerpc64le) that uses a script to scan and fix each package.
