Subject: Link against libm to avoid Python related linking errors.
X-Git-Tag: libsigrokdecode-0.3.0~165

Link against libm to avoid Python related linking errors.

The python3-config script reported "-lm" as linker option previously,
but we switched to using pkg-config (among other things for
cross-compile support) which doesn't report "-lm" though (this is a
common behaviour across multiple distros and OSes).
