>Description:
www/firefox build fails as follows:

    INPUT("../../gfx/skia/Unified_cpp_gfx_skia7.o")
    INPUT("../../gfx/skia/Unified_cpp_gfx_skia8.o")
    INPUT("../../gfx/skia/Unified_cpp_gfx_skia9.o")
    INPUT("StaticXULComponentsEnd/StaticXULComponentsEnd.o")

ld: ../../xpcom/components/nsComponentManager.o: relocation R_X86_64_PC32 against protected symbol `end_kPStaticModules_NSModule' can not be used when making a shared object
ld: final link failed: Bad value
/usr/tmp/pkgsrc/www/firefox/work/firefox-44.0/config/rules.mk:827: recipe for target 'libxul.so' failed
gmake[3]: *** [libxul.so] Error 1

$ ld -v
GNU ld (NetBSD Binutils nb1) 2.26.20160125

With older ld from NetBSD base, it builds successfully.

>How-To-Repeat:
On NetBSD/amd64 current of yesterday:
$ cd /usr/pkgsrc/www/firefox
$ make

>Fix:
	
I have no idea.
