Set TARGET_LIBGCC to -lgcc instead of full libgcc.a path
Because
1. "$(TARGET_CC) -print-libgcc-file-name" doesn't get specialized
libgcc.a, although with proper flags like "-march=armv7-a" and
"-mthumb" it does.
2. When TARGET_CC is clang and -gcc-toolchain points to correct
GCC 4.6 directory, "$(TARGET_CC) -print-libgcc-file-name"
prints only libgcc.a w/o path (ie. a bug in clang)
This bug didn't reveal because TARGET-get-linker-objects-and-libraries
was called too early before TARGET_LIBGCC is set
