libmap.conf(5) manual page documents how to restrict such mappings per-directory.
One can create symlink for the interpreter and restrict the mapping for symlink only.

Not quite: libgcc_s.so.1 needs mapping for interpreter only as our port building system
already creates libgfortran.so with right rpath for libgcc_s.so.1:

# ldd /usr/local/lib/gcc8/libgfortran.so.5
/usr/local/lib/gcc8/libgfortran.so.5:
        libquadmath.so.0 => /usr/local/lib/gcc8/libquadmath.so.0 (0x80146e000)
        libz.so.6 => /lib/libz.so.6 (0x8016ad000)
        libm.so.5 => /lib/libm.so.5 (0x8018c5000)
        libgcc_s.so.1 => /usr/local/lib/gcc8/libgcc_s.so.1 (0x801af3000)
        libc.so.7 => /lib/libc.so.7 (0x800823000)
