elf.machine can hold any value from the ELF header, but the module only
named 14 of them, so a rule targeting anything else had to hardcode the
number or drop the module and match the header bytes by hand.
Add the architectures from the issue: PARISC, SPARC32PLUS, S390, MCORE,
SH, SPARCV9, ARC_COMPACT, BPF and LOONGARCH.
0x27 is exposed under both EM_MCORE and EM_RCE. EM_RCE is the name it was
originally registered under and still what some toolchains emit, so a rule
written against either name works.
