Configure Fix
Description:
Modified configure to set FC and CXX to "no" when fortran and c++ are
not being compiled, respectively. This will prevent configure from running
some checks on these compilers when they are not being used.
This fixes a problem that was occuring when FC and/or CXX are set to
a nonexistant or invalid compiler. Even if the languages were disabled,
a libtool test would fail, thus preventing libtool from properly linking
any libraries, yet configure would not flag an error message due to this
because the languages were disabled.
Tested:
- h5committest (jam, smirom, linew)
- manually eyeballed configure output and logfile.
