The correct Tcl syntax would be:

pre-configure {
    set libgfortran [exec ${configure.fc} --print-file-name libgfortran.a]
    configure.ldflags-append "-L[file dirname ${libgfortran}]"
}

I removed "-lgfortran", assuming the build system already does that. If it does not, then it would be simpler to just pass the complete path to the library, rather than passing a -L flag to its directory and a -l path to its name.

configure.fc
