Definitely not a problem of tip core/rseq. It just ends up in
__get_user_asm2() and then the compiler gets unhappy about the PowerPC
inline assembly for whatever reason.

I see it is a CLANG build.
CLANG might be less flexible, can you test with following change ?
diff --git a/arch/powerpc/include/asm/uaccess.h

That avoids the error for me. I notice that this does not reproduce
beyond clang-16 for me so I am going to bisect LLVM to see what fixes
this error.

Oh, it is because of commit e2ffa15b9baa ("kbuild: Disable
CC_HAS_ASM_GOTO_OUTPUT on clang < 17"). Prior to that change, all
supported versions of clang would use the CONFIG_CC_HAS_ASM_GOTO_OUTPUT
blocks in arch/powerpc/include/asm/uaccess.h, whereas now clang-15 and
clang-16 will use the variants without asm goto with outputs.
Cheers,
Nathan
