[Buildroot] [PATCH] toolchain: have check_glibc to search deeper for ld-linux

[Jean-Mickael Guerin]

ld-linux*.so may not be present in lib/ directory, it could be
in lib32 and/or lib64 only. But check_glibc reports
"Incorrect selection of the C library" in this case, which is
not true.
Fixed by extending the search to  SYSROOT/*/*.
