INTMAX_TYPE and UINTMAX_TYPE are always in terms of long long on
OpenBSD, regardless of the size of a long.

Upgrade procedure if you don't want to use the damn snapshots:
- build and install new kernel, reboot off it
- build new gcc, do not install it yet
- make includes
- install new gcc
- build and install lib/csu and lib/libc
- make build

Do not align jump targets to cache line boundaries at -O2 on OpenBSD.

OpenBSD defaults to dynamic linker of /usr/libexec/ld.so

Yes, openbsd does not support shared libraries on sh yet, but why make it hard?

Move back to softfloat for now.

Use __start (the symbol we provide) not start. ok miod@

Default to -m4.

Define superH obsd-specific emulations for ld, and use it by default.

Early bits for a 32-bit SuperH toolchain, currently for little-endian
systems only; more work is necessary in ld land.
