[Support #GHO-258559]: udunits installation problem

I suspect that the Standard C library function ceil(3) is in a "math" library
(e.g., "libm") rather than the Standard C library (e.g., "libc").  See if you
can find the ceil(3) function by using the "nm -g" command against the libraries
in /lib and /usr/lib.  When you find it, you should add an ld(1)-style reference
to it to the environment variable LD_MATH before executing the configure(1)
script (again).  For example:

    $ make distclean
    $ CPPFLAGS=-DpgiFortran LD_MATH=-lm ./configure >configure.log 2>&1
