Should we link to libm?

[KristofferC]

Looking at the sysimage that comes with julia, it links with libm:

❯ ldd sys.so 
        linux-vdso.so.1 (0x00007ffe7819d000)
        libjulia-internal.so.1 => not found
        libjulia.so.1 => not found
        libstdc++.so.6 => /lib/x86_64-linux-gnu/libstdc++.so.6 (0x00007f4147fa7000)
        libm.so.6 => /lib/x86_64-linux-gnu/libm.so.6 (0x00007f4147e59000)
        libgcc_s.so.1 => /lib/x86_64-linux-gnu/libgcc_s.so.1 (0x00007f4147e3e000)
        libc.so.6 => /lib/x86_64-linux-gnu/libc.so.6 (0x00007f4147c52000)
        /lib64/ld-linux-x86-64.so.2 (0x00007f4151a29000)

But the ones from PackageCompiler does not:

❯ ldd sys.so # PackageCompiler sysimage
        linux-vdso.so.1 (0x00007fff7b6e7000)
        libjulia-internal.so.1 => not found
        libjulia.so.1 => not found
        libc.so.6 => /lib/x86_64-linux-gnu/libc.so.6 (0x00007fa75e9de000)
        /lib64/ld-linux-x86-64.so.2 (0x00007fa76790c000)

Perhaps this is the cause of https://discourse.julialang.org/t/packagecompiler-create-app-function-failing-on-slurm-cluster-error-undefined-reference-to-ceil/69344? We should figure out what causes the difference is between the sysimage provided by PackageCompiler and the official distribution.
