compiled/linked with -O2 -pie -fpie on various arches either doesn't link at
all,
or makes completely unnecessarily a DT_TEXTREL PIE. Tried x86_64, i386, ppc,
ppc64. For the TLS transitions and relocations, PIEs should be handled like
other executables, so many info->shared checks need to be replaced with
!info->executable. For the TLS relocations, even when the executable is
position independent, the offsets within the PIE's TLS block are known at link
time and so relocations like R_X86_64_TPOFF32 can be relocated fully at link
time.
