>Description:
print/acroread8 doesn't work in linux32 emulation on amd64.
When starting it, the error message is:
cannot set up thread-local storage: cannot set up LDT for thread-local storage

Nicolas Joly says that it needs the modify_ldt(2) syscall, but that
depends on the USER_LDT kernel option, which NetBSD/amd64 currently
doesn't support.
>How-To-Repeat:
cd /usr/pkgsrc/print/acroread8
make install
acroread8
>Fix:
Probably: Implement modify_ldt(2) for linux32 emulation.
