commit 57b9a433e13d7062eca4bd8fbae80019a499e973
Author: Herbert Valerio Riedel <hvr at gnu.org>
Date:   Mon Mar 5 21:13:28 2018 +0100

    Fixup include of gmp/config.mk to use new location
    
    This wasn't spotted rightaway in
    8f0b2f5eadf0fcb47c581907205a9db686214a69
    because the include-site deliberately ignored include-errors as
    a Hack with the justification below:
    
    > Hack. The file gmp/config.mk doesn't exist yet after running ./configure in
    > the toplevel (ghc) directory. To let some toplevel make commands such as
    > sdist go through, right after ./configure, don't consider this an error.
    
    This may have contributed to #14891.
    
    (cherry picked from commit df7ac37d43bdbabbde9b09344f9425e8e5a879ff)
