patch to fix the bug

This seems to fix the issue, but there may be additional reloc types that
should be checked to fully fix it.

[Bug ld/21017] New: [microblaze] ld fails with missing _GLOBAL_OFFSET_TABLE_ symbol when all relocs are @GOTOFF

2017-01-02 Thread bugdal at aerifal dot cx 
https://sourceware.org/bugzilla/show_bug.cgi?id=21017

Bug ID: 21017
   Summary: [microblaze] ld fails with missing
_GLOBAL_OFFSET_TABLE_ symbol when all relocs are
@GOTOFF
   Product: binutils
   Version: unspecified
Status: UNCONFIRMED
  Severity: normal
  Priority: P2
 Component: ld
  Assignee: unassigned at sourceware dot org
  Reporter: bugdal at aerifal dot cx
  Target Milestone: ---

When linking a program where all GOT-based relocations are GOT-relative rather
than GOT slots, create_got_section is never called and linking fails due to
missing _GLOBAL_OFFSET_TABLE_ symbol. This was found to happen when static
linking non-PIC code with musl libc's crt1 which contains (gratuitous for
non-pie, but not erroneous) logic to compute the address of _DYNAMIC if it's
defined, but it probably can also happen in other situations where most object
files are non-PIC but one contains PIC code with only GOT-relative relocations.

I don't believe there were any regressions.   Will retest ,

I believe the glibc issue must be fixed as I had successful builds in the
latter part of
last October when I was hacking on it.

Happy New Years,
