avis-client-c: ceilf, linking with -lm

[Daniel Pocock]

I've observed this binary linking successfully on Debian but not on
Ubuntu.  The package uses an autotools build system.

On Ubuntu, gcc link complains about unresolved reference to ceilf, even
though -lm is in the linker command line

Can anybody comment on the correct way to go about this?  On both
platforms, autoreconf is executed as part of the package build from
debian/rules and there is one patch against configure.ac, for supporting
HURD and kFreeBSD kernels.
