Not that I know of. You can get perl5's guess by looking at
$Config{libc}, but that value could be empty or wrong. If you want to be
either amused or amazed, you can look at the complex gyrations perl5's
Configure tries to go through to find the C library, but even that isn't
always right. Further, perl5's Configure only looks for the libc name if
it is necessary. Often, it is sufficient (for Configure's purpose) to let
the compiler find the C library. As one example, it's conceivable that
the compiler might use the C library in either /lib32/ for /lib64/,
depending on compiler flags and environment variables.
