[PATCH] nativesdk-glibc: Extend relocation support to locales

[PATCH] nativesdk-glibc: Extend relocation support to locales

[Richard Purdie]

Currently locales are not found in a relocated buildtools-tarball
such as that used in eSDK. This breaks bitbake when used under python3.

This patch adds enough relocation magic to nativesdk-glibc so that
the binary locales can be found even in a relocated buildtools-tarball
and bitbake works successfully under python3. The eSDK also works 
correctly after this change too.
