build: Derive object names in make_sunver.pl

Browse Source 
The recent move of libgfortran object files to subdirs and the resulting
breakage of libgfortran.so symbol exports demonstrated how fragile
deriving object and archive names from their libtool counterparts in the
Makefiles is.  Therefore, this patch moves that step into
make_sunver.pl, considerably simplifying the Makefile rules to create
the version scripts.

Bootstrapped without regressions on i386-pc-solaris2.11 and
sparc-sun-solaris2.11, verifying that the version scripts are identical
except for the input filenames.
