New package: gprbuild-25.0.0

[Tevo45]

GPRbuild is a multi-language build system commonly found in Ada projects. Changes include xmlada and gprconfig_kb, both dependencies of gprbuild, as well as libgpr, an optional library component. Lightly tested, but should receive some more usage in the coming days.

Closes #45421

I hadn't noticed it before, since libgpr-devel was missing a dependency on libgpr, but it seems I cannot install the built libgpr package due to "broken, unresolvable shlib"s on xmlada's libraries?

tenshi$ sudo xbps-install --repository hostdir/binpkgs/gprbuild libgpr
Password: 
libgpr-25.0.0_1: broken, unresolvable shlib `libxmlada_dom.so.18.0w'

libgpr-25.0.0_1: broken, unresolvable shlib `libxmlada_sax.so.18.0w'
libgpr-25.0.0_1: broken, unresolvable shlib `libxmlada_schema.so.18.0w'
libgpr-25.0.0_1: broken, unresolvable shlib `libxmlada_unicode.so.18.0w'
Transaction aborted due to unresolved shlibs.

I'm not exactly sure why; xmlada's shared objects are listed on common/shlibs, and the soname for those listed on the built libgpr.so seems to match exactly:

tenshi$ readelf -d libgnatprj.so

Dynamic section at offset 0x63ad40 contains 35 entries:

I've tried adding xmlada to libgpr's depends, and adding xmlada's libraries' full path to common/shlibs (i.e. /usr/lib/xmlada/xmlada_schema.relocatable/libxmlada_schema.so.18.0w, etc) without much luck.

Following the example from Fedora, I've also renamed libgpr.so to libgnatprj.so, to avoid conflict with gRPC's libgpr.

[Tevo45]

I haven't made any effort to investigate the installation failure for libgpr, but gprbuild itself has been working fine for me. I figure if nobody minds we could just drop libgpr for the time being, and revisit it once somebody feels the need.

It's still using the host gcc for cross-builds.
