About gmp and mpfr dependencies for gdb building

Hi,

For the gmp and mpfr dependency libs, is it possible to provide an option
to enable/disable the gmp and mpfr instead of forcely enabling them when
building gdb?

Sometimes, we would like to cross compile the gdb in the crash-utility, but
we did not run into any issues before upgrading to gdb 16.2.

BTW: crash-utility used gdb-10.2 before upgrading to gdb-16.2

Any ideas or suggestions?


Thanks
