other/823: gcc -U does not undef a macro

[Neil Booth]

Hi Richard,

It does actually undefine it, but it gets processed before -D :-(

This is a gcc.c specs issue; I don't think fixing it is entirely
trivial.  We need gcc.c to pass all -D and -U options in the order
they appear, and not to group them like it currently does.

Neil.
