[PATCH] Makefile: Disable PLATFORM_LIBGCC for LLVM toolchain

[Alistair Delva]

The LLVM toolchain does not have or need libgcc, so do not require
it to exist on the library path. Even if "-print-libgcc-file-name"
returned the empty string, -lgcc would be specified.

This leaves CONFIG_USE_PRIVATE_LIBGCC alone because I did not have
a target/toolchain combination available for testing.
