[svn-r11514] Purpose:

Bug fix

Description:
Fixed config file for apple powerpcs.  Should detect xlf more
often (though not infallibly).
Should disable shared libraries when xlf is being used.

Solution:
Since neither xlf nor f95 have "version" options (which could
be used to identify which compiler is being used), the config
file checks if the fortran compiler is named 'xlf' (or /path/xlf).
If not, it assumes the compiler must be f95.
xlf is still the default if no compiler is named at all.

Platforms tested:
pommier (change only to mac-specific config file)
