Re: git: aca928a50a42 - main - zfs: merge openzfs/zfs@e2357561b

This seems to break macos bootstrap:

% ./tools/build/make.py TARGET=arm64 TARGET_ARCH=aarch64 -DNOCLEAN
buildworld -j 20
...
--- assert.o ---
/Users/imp/git/head/sys/contrib/openzfs/lib/libspl/assert.c:70:1: error:
redefinition of 'libspl_gettid'
libspl_gettid(void)
^
/Users/imp/git/head/sys/contrib/openzfs/lib/libspl/assert.c:57:1: note:
previous definition is here
libspl_gettid(void)
^
1 error generated.
*** [assert.o] Error code 1

bmake[3]: stopped in /Users/imp/git/head/cddl/lib/libspl
bmake[3]: 1 error

Looks like two identical copies of
#if defined(__APPLE__)
static inline uint64_t
libspl_gettid(void)
{
uint64_t tid;

if (pthread_threadid_np(NULL, &tid) != 0)
tid = 0;

return (tid);
}
#endif

which normally aren't compiled on !macos. Removing one fixes the issue.
Should I just commit because this is a mismerge, or should I let you take
care of it with upstream?
