Subject: package/gawk: clean the mpfr dependency
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=a3fd70c0431a8905ff7840071373265d8fe28229;p=buildroot.git

package/gawk: clean the mpfr dependency

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.
