-fbracket-depth is not a valid option in gcc #18

In tools/Makefile, -fbracket-depth is in $CFLAGS under gcc-pre. This is not a valid option according to man gcc (although some searching suggests that it is available in some forks), which prevents gcc from being built on my linux (Gentoo) host, reported as: error: C compiler cannot create executables Removing this option solves this problem on my host.

A result of an inadvertent addition of a clang flag to the default. Now fixed.
