firefox on sparc64

[Sad Clouds <cryintothebluesky%googlemail.com@localhost>]

Hello it looks like firefox should work on sparc64

http://blog.netbsd.org/tnf/entry/firefox_on_sparc64

I recently built firefox-22.0 on sparc64 (took 3 days to compile
on Ultra10), but it fails to start and prints the following error

(process:19276): GLib-CRITICAL **: g_slice_set_config: assertion
`sys_page_size == 0' failed

Anyone else seen this issue?
