The PowerPC PE support is so old and bitrotted that it ought to be
removed. Test results for a cross from x86_64 with no C cross
compiler currently shows 109 fails. I don't think anyone cares about
the target.
This FIXME in bfd/peXXigen.c has been around since 1999, git commit
277d1b5e453:
/* FIXME: This file has various tests of POWERPC_LE_PE. Those tests
worked when the code was in peicode.h, but no longer work now that
the code is in peigen.c. PowerPC NT is said to be dead. If
anybody wants to revive the code, you will have to figure out how
to handle those issues. */
and this one in gas/config/tc-ppc.c since 1995, git commit
cd557d83d61:
* FIXME: I just noticed this. This doesn't work at all really. It it
* setting bits that bfd probably neither understands or uses. The
* correct approach (?) will have to incorporate extra fields attached
* to the section to hold the system specific stuff. (krk)
* config.bfd: Obsolete powerpcle-*-pe targets.

For ppc64 I set flags when recording the dynamic relocation rather
than when allocating space. That allows you to distinguish three
cases:
1) The dynamic ifunc relocation is in an executable and will always be
to an ifunc resolver in the executable.
2) The dynamic ifunc relocation is in a shared library which provides
an ifunc resolver, but that may be overridden at runtime to use a
resolver in another binary.
3) The dynamic ifunc relocation is not to a locally defined ifunc
resolver.
Case (3) won't cause a segfault trying to run resolver code that is
non-exec on older glibc.
I made case (1) an error for ppc64, but since newer glibc ld.so does
allow running ifunc resolvers when segments are writable I suppose I
should downgrade that to a warning like case (2).

Don't do anything special with non-loaded, non-alloced sections.
In particular, any relocs in such sections should not affect GOT
and PLT reference counting (ie. we don't allow them to create GOT
or PLT entries), there's no possibility or desire to optimize TLS
relocs, and there's not much point in propagating relocs to shared
libs that the dynamic linker won't relocate.
Since check_relocs is no longer called on non-loaded, non-alloced
sections, remove SEC_ALLOC check. Resolve relocation in debug section
against symbol defined in shared library to 0.
