This reverts commit 593fe01b.

Binaries in binutils-armhf etc. break the build system:

Error loading shared library libopcodes-2.32.so: Exec format error (needed by /usr/bin/as)
Error loading shared library libbfd-2.32.so: Exec format error (needed by /usr/bin/as)
Error loading shared library libz.so.1: Exec format error (needed by /usr/bin/as)
Error relocating /usr/bin/as: bfd_errmsg: symbol not found
Error relocating /usr/bin/as: deflateEnd: symbol not found
Error relocating /usr/bin/as: bfd_arch_bits_per_address: symbol not found
Error relocating /usr/bin/as: bfd_set_error_program_name: symbol not found
Error relocating /usr/bin/as: xcalloc: symbol not found

Reverting for now. The upstream compatibility CI test is expected to fail.
The postmarketOS binary repositories still have the old binutils package.

I'm analyzing this issue in #295.
