5be920e910 s390x: don't allow br r0 in CRTJMP asm
The instruction encoding that would be "br %r0" is not actually a
branch to r0, but instead a nop/memory-barrier. gcc 14 has been found
to choose r0 for the "r"(pc) constraint, breaking CRTJMP.

This patch adjusts the inline assembly constraints and marks "pc" as
address ("a"), which disallows usage of r0.

4d3a162d00 remove use of endian.h from arch reloc.h headers, clean up
building on commit 97d35a552e,
__BYTE_ORDER is now available wherever alltypes.h is included. since
reloc.h is only used from src/internal/dynlink.h, it can be assumed
that __BYTE_ORDER is exposed. reloc.h is not permitted to be included
in other contexts, and generally, like most arch headers, lacks
inclusion guards that would allow such usage. the mips64 version
mistakenly included such guards; they are removed for consistency.
