There is a new pull request by tornaria against master on the void-packages repository

https://github.com/tornaria/void-packages gmpy2
https://github.com/void-linux/void-packages/pull/33481

python3-gmpy2: restore package
Upstream 2.1.0rc1 builds on python3.10.

This package is used by python3-mpmath for multiprecission arithmetic.
If not installed, mpmath defaults to python bigints which are very slow.

For example: compute 1M digits of pi using sympy:

$ isympy	# without python3-gmpy2
In [1]: %time a=pi.n(1_000_000)
CPU times: user 49.4 s, sys: 2.96 ms, total: 49.4 s
Wall time: 49.4 s

vs.

$ isympy	# with python3-gmpy2
In [1]: %time a=pi.n(1_000_000)
CPU times: user 632 ms, sys: 5.99 ms, total: 638 ms
Wall time: 639 ms

Note that just installing python3-gmpy2 brings this improvement.
Arguably python3-gmpy2 could be made a dependency of python3-mpmath.

This reverts commit f91cea99ddace872a5cdf0ae5d93fcc15b2f3191.

Also:
 - fix hostmakedepends
 - make tests work
 - adopt

A patch file from https://github.com/void-linux/void-packages/pull/33481.patch is attached
