Fix uClibc build for noMMU target

Browse Source 
uclibc_backend_once tries to build dummy shared libraries regardless of
whether shared libraries support for target is enabled or not, resulting
in build failure in noMMU bFLT configuration.
Only build dummy shared libraries when shared library support for target
is enabled.
