mkhybrid is an easy diff.
gcc uses them for precompiled headers (PCH) which is a local diff added by
kurt@ in 2009. its likely nothing in base uses PCH but i don’t know what in
ports needs this:
https://github.com/openbsd/src/commit/cfee5d1
choices there would be to disable PCH support or maybe there’s a different way
to reimplement without brk/sbrk.
clang looks like they have a HAVE_SBRK ifdef or something like that. so usage
can likely be turned off but i don’t know this codebase that well so that’s
just an assumption.
