meson: Fix gnulib build where isnan*() is needed
Hi,
As there are some changes in how isnan*() is being detected, we need to include the isnan*.c sources if any of the isnan*() functions are missing, so that linking the GLib .so/DLL will not fail if the isnan*()
functions are not adequately supported by the compiler's CRT and/or headers.
With blessings, thank you!
