 revision="df7ac37d43bdbabbde9b09344f9425e8e5a879ff"
 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.
