When available, mpfr provides support for BIGNUM, which allows gawk to
work on arbitrarily-large numbers (hence the name).

Forcibly disable mpfr if the mpfr package is not enabled. Let
./configure find it automatically when it is enabled.

To be noted, the host-gawk need not have BIGNUM to build the target
variant with support for BIGNUM.
