This patch seems to have broken slepc[1], slepc-complex[2] and
randomjungle[3].

For randomjungle the config.log tells me this:

I’ll investigate this.  It’s odd that “-lgfortran” cannot be found only
because we deleted useless wrappers.

I found that for randomjungle the native inputs must now also include

    ("gfortran" ,gfortran "lib")

in *addition* to the usual

    ("gfortran" ,gfortran)

I can prepare a patch for the three broken packages, but I wonder why
this is necessary.  “gfortran” alone does not install “libgfortran.so”,
only the “lib” output does.

For GCC we hack the “lib” spec (as show by ‘gcc -dumpspecs’) so that it
has an extra -L for libgcc_s (search for ‘GNU_USER_TARGET_LIB_SPEC’ in
gcc.scm).

Should something similar be done here?
