Summary

devel/liberasurecode: exorcise -Werror more throughly

Looks like upstream put a few more in after I took out all of
them in the previous commit.  This fixes the build with LLVM 15,
which takes offence in declaring parameterless function as foo()
instead of foo(void).

Test Plan

Tested on i386 amd64 FreeBSD 12.4 13.1. arm64 pending.
See http://fuz.su/~fuz/freebsd/batch1/

[eduardo]

• Consider bump PORTREVISION since some changes will affect build
• Define LICENSE_FILE since it's included in tarball https://docs.freebsd.org/en/books/porters-handbook/book/#licenses-license
• Missing Approved by: .. (mentors) field in Summary/commit msg

[fuz]

As per guidance from eduardo:

• defined LICENSE_FILE
• bump PORTREVISION

Fix typo in PORTREVISION

[eduardo]

Since this is a build fix we don't need maintainer approval and that can be Approved by: portmgr blanket (buildfix)

devel/liberasurecode/Makefile

3

Should be set to 1, since last PORTREVISION is 0

[fuz]

I am the maintainer. No need to appeal to the blanket approval.
