Set CTARGET and CTARGET_ARCH on top of the generated APKBUILD and use
the existing code in the APKBUILD for build(), package(), makedepends,
subpackages. This is now possible, because the pmbootstrap parser for
APKBUILDs has been improved a lot since this was originally written and
because the Alpine APKBUILD does everything that was hacked in here,
like removing man, info directories and bfd-plugins if doing a cross
build.
This is now very similar to bootstrapping binutils for another
architecture via scripts/bootstrap.sh in aports.git.
Most importantly this sets --disable-gprofng, which fails to build
against musl and is the reason why our cross/binutils-* packages
generated from binutils 2.39.x didn't build anymore.

Newly generated binutils package has file conflicsts with
non-cross binutils.
ERROR: binutils-2.37-r3: trying to overwrite usr/lib/bfd-plugins/libdep.so
owned by binutils-aarch64-2.37-r3.
Fix the generator to produce package that does not include these plugins.
Packages like binutils-*, busybox-static-*, gcc-*, grub-efi-*, musl-*
are only needed for the native architecture during cross compilation.
Don't bother with trying to build them for other arches to save time and
to avoid getting stuck frequently at "armv7/binutils-aarch64" etc.
A few people like to use pmbootstrap on aarch64 hosts (e.g. PineBook
Pro), so let's make it available for aarch64 again when we can build
aarch64 packages natively in CI and bpo. (They do get stuck there right
now, because of qemu user emulation.)

APKBUILD should be indented with tabs not spaces.
This also resolves a bug which the replace_functions feature was always
trimming off the beginning of a line.
For example:
replace_functions = {"build": "return 0"}
would be formatted as "rn 0".
test_aportgen.py fails because some test data is missing.
Make the test pass by fixing the test data with the following changes:
- Update testdata pmaports/cross/*
- Don't git ignore test/testdata/aportgen directory
- Add testdata aports/main/* from upstream Alpine Linux aports
Patch files in pmaports/cross/binutils-armhf were removed, as they are
not needed to test the pmbootstrap code.
