I've applied this patch to update the MIPS port for the syscall-list
changes in libc, so that triarch headers are still generated correctly
after those changes.
I think tilegx should properly be updated to have the right definitions as
a biarch port - even if there are no differences for lib-names.h or
syscall.h between the 32-bit and 64-bit cases, each should still get its
own stubs.h generated.

In fact, syscall.h was problematic, since by default we were only getting
the -m64 names, not the -m32 names. I added a
sysdeps/unix/sysv/linux/tile/tilegx/Makefile that has:
+ifeq ($(subdir),misc)
+
+# Provide biarch definitions.
+abi-variants := 64 32
+abi-64-options := -D__LP64__
+abi-64-condition := __WORDSIZE == 64
+abi-32-options := -U__LP64__
+abi-32-condition := __WORDSIZE == 32
+
+endif
I pushed this, along with some other changes to catch up with recent work:

For stubs.h to work correctly you should also have default-abi definitions
in appropriate files for each ABI.

Thanks, I pushed appropriate Makefile changes.
