At least it compiles again, after adding asm prefix and ptrace/sysctl...
Hacked it in for now, but needs a better patch for runtime and syscall.
Still fails to actually run, but

There is the other big change needed, which is to prefix all the asm names
with USER_LABEL_PREFIX (_) so that they will actually link properly later.

It still needs to generate the extra underscore for Darwin,
and it still needs to fix the bug mentioned in Comment #12.

Then it's more about fixing library issues, like the macros used
for TIOCNOTTY/TIOCSCTTY or st_atime/st_mtime/st_ctime and sysctl.

The whole patch is Darwin-centric, in that it's only applied on Darwin.
You are right that it first needs to be conditionalized to go upstream.
afaik, $(OTOOL) would be somethin

Here's my attempt at a native version.

Instead of the default variant:

$OBJCOPY -j .go_export $1 $2
