Hello!

I have strange problem with Mozilla Firefox on FreeBSD/sparc64.
Segmentation fault encountered when running Mozilla Firefox.
The problem is described here:
<http://www.freebsd.org/cgi/query-pr.cgi?pr=89486sparc64>
<https://bugzilla.mozilla.org/show_bug.cgi?id=320063>

The problem in bogus relocations in the PLT (The 3 R_SPARC_NONE *ABS* relocs).

$ objdump -RC firefox-bin

firefox-bin:     file format elf64-sparc
