[tlbuild] icu build fails on FreeBSD-5/i386: problem with pthread lib?

Hello,

libs/icu (r17501) fails to build on oldish FreeBSD-5, on i386 only,
development tree only. amd64 is ok, TL2009 sources are ok too.

It fails because binaries generated during build segfault (at various
occasions makeconv, gennames, genrb...), like this:

Segmentation fault (core dumped)
--------------------------------- >8 ---------------------------------

The problem seems to be related to libpthread and all icu binaries are
linked against it. Please find ldd info and gdb output against
makeconv.core, gennames.core and genrb.core below.

However, as far as I understand, icu components are not supposed to be
linked against any threading library, according to the comment in the
Build script. If that idea covers binaries as well, it does not happen
on FreeBSD.

(Anyway, any use of -lpthread is incorrect on FreeBSD; -pthread should
be use instead. The official port (devel/icu4) treats icu sources like
this:
1. patches config/mh-bsd-gcc to use PTHREAD_CFLAGS as THREADSCPPFLAGS,
   which defaults to nothing, e.g. -D_REENTRANT is removed;
2. patches runConfigureICU like this:
     http://www.freebsd.org/cgi/cvsweb.cgi/ports/devel/icu4/files/patch-cc-flags?rev=1.2;content-type=text%2Fx-cvsweb-markup
3. use '--enable-threads=no' or '--enable-weak-threads' depending on
   user's settings.)

What can be done here? Is linking to pthread lib necessary or
intentional?
