Message:

Experimental change - Added -B/usr/bin to compiler flags for GCC Pass 1 - should result in a fix for the problem we encountered with LFS 5.1.1 building an older toolchain from a newer.

+supported by our new linker, causing compilation errors.  By passing the -B
+flag to gcc, we cause the compiler to temporarily use the host's linker,
