nativesdk: Set LIBCOVERRIDE to a value

nativesdk was just unsetting LIBCOVERRIDE however that causes some build failures
for xorg-libs which used a libc override. This adds in a mechanism to force
nativesdk to glibc and give the option of allowing another selection like
uclibc if anyone ever does the work to make it operational.
