[svn-r2198] Figure out the whole path of the $CC command if it is in simple

command form (e.g., cc, gcc) and put that in the libhdf5.settings
file.  This would help show exactly which compiler was used during
the configure stage.  It may not be 100% "correct" in some cases
such as "configure done in one machine but compiling done in another."
