[PATCH v3 4/4] libcc1: 'set debug compile': Display absolute GCC driver filename

[Jan Kratochvil]

Hi,

already approved, maybe it could be already checked in outside of the series:
        https://gcc.gnu.org/ml/gcc-patches/2015-04/msg01298.html

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.
