Subject: [PATCH 05/30] nativesdk-glibc: Make relocatable install for locales

The glibc locale path is hard-coded to the install prefix, but in SDKs we need
to be able to relocate the binaries.  Expand the strings to 4K and put them in a
magic segment that we can relocate at install time.

Upstream-Status: Inappropriate (OE-specific)
