The CI failure - complaints of this nature
==> Error: Failed to install py-torch due to ExtrapolationError: Can't extrapolate a URL for version 2.7.1 because package py-torch defines no URLs
look unrelated to this PR.

…pack#2926) (spack#51) Some example targets (e.g. v4l2) use math functions such as sin(), but libm was not listed explicitly on the link line. Older toolchains linked this transitively, but newer GCC/binutils reject this with “DSO missing from command line”. Add -lm explicitly to make the link robust and portable.

Note
This PR was migrated from spack/spack#49318.
Not tested, but this is inspired by what's in the
mpichrecipe. This should hopefully allow building openmpi without a fortran compiler, if the user only wants to run non-Fortran code with openmpi.
