xlC link errors caused by commas in BUILDDIR
I've run into a linker error when building with IBM XLC++
in a directory whose name contains a comma (see below).
The problem is that we're passing the absolute pathname
of $BUILDDIR/lib to the linker via the -Wl compiler driver
option. This option uses the comma to separate individual
arguments from one another. I don't know if it's worth
trying to deal with this or not but I thought I'd mention
it in case someone else runs into the same problem or in
case Andrew has an idea for how to fix it.

Spaces in file names are known not to work on UNIX in general
because they are reserved by all utilities to separate command
line arguments and options. Commas are not reserved by most
utilities and they are handled fine in most cases so when they
don't work it's likely to be surprising to users, especially
if they don't cause any problems in archive builds (they don't
appear to).

Greetings Martin.
For what it's worth, this isn't a problem restricted to XLC++. My
reading of the .config files indicates that the only compilers that
won't be affected are the osf_cxx, Sunpro, reliant_cds, como and eccp
compilers. The first two compilers don't use a comma in the rpath
option, and the remainder don't have an rpath switch defined.
It might be possible to alter the makefiles to mangle the path, escaping
the comma, but I suspect that could cause other problems. I would
hazard a guess that spaces in the value of $BUILDDIR might also cause a
number of problems.
