[Bug 873013] [NEW] perl fails to cross-build

[Wookey]

Public bug reported:

perl fails to cross-build with a lot of undefined references to pthread*

util.o: In function `Perl_die_nocontext':
/home/wookey/testing/build/build/xdeb/perl/util.c:1397: undefined reference to `pthread_getspecific'

A lot of work has been done on perl to make it cross-build and with that
(1.3MB) patch applied it gets quite a long way, but something is still
amiss with pthread.

Other people have had this working, so further investigation is needed
to determine what exactly is still going wrong in this environement.

Background:
The build command is:
xdeb --only-explicit -a armel --prefer-apt --apt-source --debug --force-rebuild bash

The actual build command xdeb issues is:
debuild --no-lintian -eUSER -eCONFIG_SITE=/etc/dpkg-cross/cross-config.armel -eDEB_BUILD_OPTIONS=nocheck -eGTEST_INCLUDEDIR=/usr/arm-linux-gnueabi/include -eGTEST_LIBDIR=/usr/arm-linux-gnueabi/lib -ePKG_CONFIG_LIBDIR=/usr/arm-linux-gnueabi/lib/pkgconfig:/usr/arm-linux-gnueabi/share/pkgconfig:/usr/share/pkgconfig -eDH_VERBOSE=1 -aarmel -b -uc -us -tc
