Comment (by kencu):

 I built Iain's current gcc11 branch on 12.3.1 Intel. It uses @rpaths
 exclusively, and it works just fine.

 example fortran program compiles with no errors:
 {{{
  % cat hello.f90
 program hello
     print *, "Hello World!"
 end program

 % gfortran-mp-11 hello.f90
 }}}
 works
 {{{
 % ./a.out
  Hello World!
 }}}

 has @rpath linkages to gcc libraries as Iain wants and requires:
 {{{
 % otool -L a.out
 a.out:
         @rpath/libgfortran.5.dylib (compatibility version 6.0.0, current
 version 6.0.0)
         @rpath/libgcc_s.1.1.dylib (compatibility version 1.0.0, current
 version 1.1.0)
         @rpath/libquadmath.0.dylib (compatibility version 1.0.0, current
 version 1.0.0)
         /usr/lib/libSystem.B.dylib (compatibility version 1.0.0, current
 version 1311.100.3)
 }}}
 but automatically adds the needed rpath search path for gcc-built
 executables to find the libraries, as Iain said it did:
 {{{
 % otool -l a.out | grep LC_RPATH -A2
           cmd LC_RPATH
       cmdsize 32
          path @loader_path (offset 12)

           cmd LC_RPATH

 So IMHO the solution to the @path issue for arm64 (now) for gcc11 would be
 to switch gcc11 on arm to Iain's gcc11 repo, current commit.
