[Qemu-devel] [PATCH] libtasn1: check if static library is present

[Laurent Vivier]

Some distros [1] don't ship systematically static libraries,
and pkg-config doesn't give us the information.

This is the case for libtasn1, so add a check in configure
to see if linker is able to find the library.
