Absolutely. Please feel free. Perl 5's Configure script is actually
public domain on purpose to encourage such sharing, so you needn't ask,
though I agree courtesy is almost never inappropriate.

You might want to revisit the gcc preferences -- they were designed to
allow Perl 5's cflags.SH to add -ansi (or -c89 or something similar) to
enforce C89 checking. I don't know if MoarVM wants to embrace that
particular constraint.
Have the appropriate amount of fun,
