libgfortran: fix buildpath QA issue
The '-fdebug-prefix-map' options are used to map source files locations,
otherwise, DW_AT_comp_dir will contain buildpath.
The '-gno-record-gcc-switches' option is used to fix the buildpath introduced
by '-fintrinsic-modules-path' option, which is automatically added by fortran.
Here's some output from 'readelf --debug-dump libgfortran.so.5.0.0' when this
option is not added:
"""
