Accept absolute paths in the -fuse-ld option.
This patch extends the -fuse-ld option to accept a full path to an executable
and use it verbatim to invoke the linker. There are generally two reasons
to desire this.
The first reason relates to the sad truth is that Clang is retargetable,
Binutils are not.
While any Clang from a binary distribution is sufficient to compile code
for a wide range of architectures and prefixed BFD linkers (e.g.
installed as /usr/bin/arm-none-linux-gnueabi-ld) as well as cross-compiled
libc's (for non-bare-metal targets) are widely available, including on all
Debian derivatives, it is impossible to use them together because
the -fuse-ld= option allows to specify neither a linker prefix nor
a full path to one.
The second reason is linker development, both when porting existing linkers
to new architectures and when working on a new linker such as LLD.
