<!-- Note: If the build is likely to take more than 2 hours, please add ci skip tag as described in

#### Local build testing
- I built this PR locally for my native architecture, (x86_64-glibc)
- I built this PR locally for these architectures (if supported. mark crossbuilds):
  - x86_64-musl
  - aarch64-musl (cross)

I replaced `guard-glibc-iconv-ext.patch` with a patch that applies equivalent changes against the 2.10.2 release, but as I'm running glibc, I don't know if the changes are necessary and sufficient on musl. At least it compiles on x86_64-musl and aarch64-musl.
