linker: ld: include crt{begin,end}.o if LIBGCC_DIR is defined

Browse source 
Only include crtbegin.o and crtend.o when LIBGCC_DIR is defined.
Since LIBGCC_DIR is not defined when compiling for posix
architecture, crt{begin,end}.o cannot be referred to via
LIBGCC_DIR.

Also note that, when using llvm/clang, crt{begin,end}S.o are
automatically for native_posix which collide with symbols in
crt{begin,end}.o. So there is no point in making LIBGCC_DIR
available for native_posix under llvm/clang.
