[PATCH 5/5] libcc1: 'set debug compile': Display absolute GCC driver filename

[Jan Kratochvil]

Hi,

with the patches so far after
	(gdb) set debug compile 1
one would get:
	searching for compiler matching regex ^(x86_64|i.86)(-[^-]*)?-linux(-gnu)?-gcc$
	found compiler x86_64-unknown-linux-gnu-gcc
But I believe it is more readable to see:
	searching for compiler matching regex ^(x86_64|i.86)(-[^-]*)?-linux(-gnu)?-gcc$
	found compiler /usr/bin/x86_64-unknown-linux-gnu-gcc

I do not think the change will have functionality impact, although the filename
gets used even for executing the command.
