ports/71967: glib20/libthr/firefox problems

[Russell McKenzie]

I also experienced apparent hangs stuck in kserel when building and  
packaging firefox on 5.3-RC1. For me, (apologies for trying 2 things at  
once) following the suggestion for libmap.conf and also removing  
jdk-1.3.1p9_4 solved the problem and I could then upgrade from  
firefox-1.0.1.p_2 to firefox-1.0.1.p_4. Can't say which one of the two did  
the trick, unfortunately. Might be worthwhile rebuilding jdk13, however I  
don't need it anymore except as an occasional build dependency.
