glibc: relocate locale paths in nativesdk

nativesdk is built with a specific prefix but this will be different at install
time, however glibc hard-codes the path to locale files. Expand these strings to 4K and move them to a magic segment which we can relocate when the SDK is installed.

+The glibc locale path is hard-coded to the install prefix, but in SDKs we need
