libhugetlbfs: Use linker wrapper during build

ld.hugetlbfs is munging certain linker commandline options
and presenting a differently named options to its users, in
summary its expecting linker process to call ld.hugetlbfs
which calls the final linker with additional decorations.

This patch makes space for that by adding -B option to compiler
so it finds this the linker in S and then we creates symlinks
for linker name that clang/gcc are expecting.

Fixes

libhugetlbfs/2.24/recipe-sysroot-native/usr/bin/x86_64-yoe-linux/x86_64-yoe-linux-ld.bfd: unrecognized option '--hugetlbfs-link=B'
