I think it is this part of the patch:

Any idea?
Yes, that is definitely the cause. I mis-understood the implications
of removing that "#ifndef __ARCH_HAS_NO_SHARED__" conditional.
I am testing a different change here that I think might do ther job better:

That fixes the alpha problem, thanks.
But now it fails for ARM FDPIC target.

Ok, this is strange. I don't see this with my ARM fdpic testing.
Can you send me your uClibc-ng .config file?
reloc_static_pie.os is only compiled if STATIC_PIE is enabled (as per
libc/misc/internals/Makefile.in) and STATIC_PIE can only be set if
!UCLIBC_FORMAT_FDPIC_ELF is true (as per extra/Configs/Config.in).
Unless I am missing something?
Regards
Greg
