Self-locate GCC driver so the toolchain works without PATH
...
The driver trusted argv[0], which requires a PATH search when it lacks
a directory component, as with w64devkit command aliases. Instead ask
Win32 for the true module path. Also search the driver's own directory
for subprograms, because as and ld live in bin/ rather than a tooldir.
Invoked by absolute path, the toolchain no longer needs its bin/ in
PATH, and remains relocatable.
