[U-Boot] [PATCH v7 14/15] spl: fix SPL build of private libgcc

[Allen Martin]

This fixes the SPL build to link with the SPL version of libgcc if
USE_PRIVATE_LIBGCC is set to "yes".  Previously it was linking with
the libgcc from the normal u-boot build because it gets set in
PLATFORM_LIBS and passed down the to the SPL build.
