You add the following to the linker flags:

-L/usr/lib/$(shell dpkg-architecture -qDEB_TARGET_GNU_TYPE)/hdf5/serial

This is wrong on i386: DEB_TARGET_GNU_TYPE expands to i686-linux-gnu,
while Debian uses i386-linux-gnu. Also, DEB_TARGET_* is definitely
wrong unless you are _building_ a cross-compiler. What you want here is
DEB_HOST_MULTIARCH - that will be correct even if you are _using_ a
cross compiler.

Also, if the package requires intrinsics, you should depend on
sse-support on i386 (but not on amd64, where SSE1 is always part of
the base ISA).

Regards,
Christian
