Arch Linux

Hi all!

Please add --enable-module-extrakeys --enable-module-schnorrsig to;

https://github.com/archlinux/svntogit-community/blob/packages/libsecp256k1/trunk/PKGBUILD#L35

Those were added in upstream:

https://github.com/bitcoin-core/secp256k1/tree/master/src/modules

And secp256k1 python package already ships bindings for these modules:

https://github.com/rustyrussell/secp256k1-py/tree/master/_cffi_build

So blockchain SDKs in python vastly use this module, it has already been done in the AUR -git package version:

https://aur.archlinux.org/packages/libsecp256k1-git#comment-850788

Also, please change pkgver=20220630+1625+g43756da over to pkgver=v0.3.1


Additional info:
* package version(s)

All the tests proposed above were tested on arch linux up to date and working on both old 20220630 version and latest upstream v0.3.1

* config and/or log files etc.

Good version of PKGBUILD attached

* link to upstream bug report, if any

Some arch users reportedly have issues on various github blockchain python repos

Steps to reproduce:

$ strings /usr/lib/libsecp256k1.so | grep secp256k1_keypair_xonly_pub

Returns nothing with current, problematic version of libsecp256k1 package version.

As such, a lot of blockchain python modules won't work, and fail to import with:

ImportError: /tmp/venv/lib/python3.11/site-packages/secp256k1/_libsecp256k1.cpython-311-x86_64-linux-gnu.so: undefined symbol: secp256k1_keypair_xonly_pub

With above PKGBUILD, this symbol (from extrakeys module) is defined, and we are up to date with v0.3.1
