LDFLAGS I presume?
I don't quite understand what is going wrong exactly.

Have you installed MacOs commandlinetools? I do have them installed.
See the first few lines of section C.3 in the R Administration and Installation manual.
And see item 2 and item 4 in the README.html in the gfortran-6.1-ElCapitan.dmg.

But you are defining too many lines in your Makevars.
I do not have F77 and FLIBS in mine. All taken care of by R's Makeconf (see /Library/Frameworks/R.framework/Versions/3.5/Resources/etc/Makeconf)
There is a symlink in /usr/local/bin/gfortran to the actual gfortran (the gfortran installer takes care of that).

I have run R CMD check on quantreg_5.35 and all is ok. No errors.
