build fails on MIPS systems

[dangowrt]

/kind bug

podman 2.2.1 fails to build on MIPS (both little and big endian, 32-bit as well as 64-bit) due to some type incompatibility.

# github.com/containers/podman/v2/pkg/signal
../../pkg/signal/signal_linux.go:46:14: undefined: unix.SIGSTKFLT

as well as

# github.com/containers/psgo/internal/dev
../../../../../dl/go-mod-cache/github.com/containers/[email protected]/internal/dev/tty.go:116:22: cannot use s.Rdev (type uint32) as type uint64 in argument to minDevNum
../../../../../dl/go-mod-cache/github.com/containers/[email protected]/internal/dev/tty.go:117:22: cannot use s.Rdev (type uint32) as type uint64 in argument to majDevNum

unix.SIGSTKFLT is that golang does not support mips

unix.SIGSTKFLT is that golang does not support mips

well, at least officially Go does support MIPS and we do build other golang package in OpenWrt and they do work.
From what I understood Go supports aarch64, arm, i386, i686, mips, mips64, mips64el, mipsel, powerpc64 and x86_64.
Ie. ppc32 and armbe being the most popular exotic ones missing in the list, but all MIPS variants are among the supported architectures.

@dangowrt I opened #8797. Can you try this please I do not have a mips system.

The other error comes from https://github.com/containers/psgo you should open an issue there.
