+Subject: [PATCH] fix: add `libc.so` fallback for musl systems to the ctypes
+ impl
+
+Add a fallback to `libc.so` library name to fix loading the ctypes
+implementation on musl systems.  On musl, `find_library("c")` does
+not work (the problem has been reported to CPython in 2014, and has not
+been resolved yet), causing the module to fail on `assert libcname`.
+Instead, add a fallback to using `libc.so` and let ctypes raise
+an exception if such a library does not exist.
