gfortran's modules are since GCC 4.9 zipped. There are two functions,
which test for the existence and absent of strings in the .mod files.
While one was updated to apply gunzip before reading, the other wasn't.
This patch copies over the unzip call from the other function. I have
tested it that it properly fails if and only if the string is present in
the (uncompressed) .mod file.
OK for the trunk?
