Work around for issue #1715
Link qemu static binaries to jemalloc. This malloc implementation does not
appear to be susceptible to the deadlock after fork issue.
This is package is meant to work around the qemu static deadlock while
cross-compiling.
- pmbootstrap binfmt_misc chroots on arm hosts are untested
- upstream jemalloc package has armv7 disabled. It is uncertain what is
wrong with jemalloc for armv7.
For these reasons, disable the arm packages.
Workaround for a build error on aarch64, where the binary package
repository is currently stuck. Compiling it for aarch64 like this:
$ pmbootstrap build --strict --arch=aarch64 qemu

Note that the only package not mentioned in both "satisfies" outputs is
curl-dev. The real questions are: why is libressl-dev getting pulled in
at all? (Alpine switched back from libressl to openssl, so this should
not happen). And why does this only happen for aarch64, but not for
x86_64 and armhf? But at least this patch unblocks the package builder.
