[Buildroot] [PATCH v12 1/1] squeezelite: new package

[Vicente Olivert Riera <Vincent.Riera@imgtec.com>]

Dear Hiroshi Kawashima,


Peter, Thomas, there is an issue commented below and I think it would be
good to have your opinion on it.

the fact that it works or not is not the problem. The problem is that
right now there isn't any official repository for that project, so that
repository could disappear tomorrow. And I don't know if the owner of
that repository has made any change to the source code or not.

Perhaps downloading the tarballs from Google Code and putting them in
mirror.buildroot.org would be the best option. I have added Peter and
Thomas on CC so they can tell their opinion about this issue.

Hiroshi, there is one more little comment below; keep scrolling down.

Well, if it doesn't work, then I guess is fine doing it by passing
CC="$(TARGET_CC)" and LD="$(TARGET_LD)" as you already do.

Vincent.
