Package: dpkg
Version: 1.13.22
Severity: serious
Justification: no longer builds from source
Hello,
Since libselinux (1.30.28-1), dpkg fails to build from source.
The failing command is the following:

In libselinux (1.30.28-1), -lpthread was added to the libselinux's pkg-config.
dpkg is statically linked against the SELinux library, thus against the
libpthread, which requires some symbols from libc.
Adding -lc (e.g. in m4/libs.m4) before -lpthread fixes this issue, but I'm
not sure it's the right way.
i.e. using:
-lc -Wl,-Bstatic `pkg-config --static --libs libselinux` -Wl,-Bdynamic
instead of:
-Wl,-Bstatic `pkg-config --static --libs libselinux` -Wl,-Bdynamic
Does anybody think it's correct?
Is there a way to fix it in the libselinux's pkg-config?
(I'm adding Manoj in CC in case he has an idea)
Kind Regards,
