This fixes the Hurd spec in the default-pie case, and adds static-pie
support.
gcc/ChangeLog:
* gcc/config/i386/gnu.h: Use PIE_SPEC, add static-pie case.
* gcc/config/i386/gnu64.h: Use PIE_SPEC, add static-pie case.
diff --git a/gcc/config/i386/gnu.h b/gcc/config/i386/gnu.h
We need the multilib paths in gcc to find e.g. glibc crt files on
Debian. This is essentially based on t-linux64 version.
gcc/ChangeLog:
* gcc/config/i386/t-gnu64: New file.
* gcc/config.gcc [x86_64-*-gnu*): Add i386/t-gnu64 to
tmake_file.
diff --git a/gcc/config.gcc
When linking with -static-pie, we need to use rcrt0.o (and grcrt0.o for
-pg). Also, set static:crt0.o before pie:Scrt1.o, otherwise -static -pie
fails to link with Scrt1.o due to missing _DYNAMIC symbol.
Also, -static-pie needs crtbeginS.o (otherwise it contains a relocation
in read-only .text).
This is notably needed because in glibc 2.34, the move of pthread functions
into libc.so happened for Linux only, not GNU/Hurd.
The pthread_self() function can also always be used fine as it is on
GNU/Hurd.

Ah, sorry, I hadn't noticed that.

I need gcc people to apply it.

The answer would be lengthy. Basically recompile gcc with it, write or
find a program that uses it, and check that it works.
But I have already done

I was able to pass glibc's complete ifunc tests with no problem.
