R11:bad84b3403f3: Mk/bsd.port.mk: Ignore @ in path in _FLAVOR_RECURSIVE_SH.
R11:e70bedf4f71e: Mk/bsd.port.mk: Don't pass up an empty flavor.

Summary

There are several ways of handling recursive targets.
I found at least

Mk/Scripts/do-depends.sh
Mk/Scripts/depends-list.sh
_FLAVOR_RECURSIVE_SH

It looks that the latter has a couple of problems comparing to others.
First, it does not handle '@' in a port name.
Second, it would set FLAVOR to the empty value even if a package is not
"flavored". That can confuse some ports.

A fast demonstration of the second problem:

$ make -C /usr/ports/lang/gcc9 checksum-recursive
...
===>   native-binutils-2.33.1_4,1 depends on file: /usr/local/sbin/pkg - found
===> Fetching all distfiles required by native-binutils-2.33.1_4,1 for building
...

Note how the package name is native-binutils instead of binutils.
A longer demonstration of the problem would be with the package-resursive target.

That issue was reported and analyzed some time ago, unfortunately with
no action: https://www.mail-archive.com/freebsd-ports@freebsd.org/msg84543.html

The proposed change brings _FLAVOR_RECURSIVE_SH closer to the other
recursion methods and it should fix both of the problems.
