[PATCH] tcg/LICENSE: Remove no-longer-true statement that TCG is BSD-licensed

[Peter Maydell]

Since 2008 the tcg/LICENSE file has not changed: it claims that
everything under tcg/ is BSD-licensed.

This is not true and hasn't been true for years: in 2013 we
accepted the tcg/aarch64 target code under a GPLv2-or-later
license statement. We don't really consider the tcg
subdirectory to be a distinct part of QEMU anyway.

Remove the LICENSE file, since claiming false information
about the license of the code is confusing, and update
the main project LICENSE file also to be clearer about
the license used by TCG.

This patch takes the simple approach of just documenting
the de-facto current reality; does anybody want to argue
for something else? Other possibilities I guess would be
specifically documenting tcg/aarch64 as an accidental
exception to the general licensing rule for tcg/, or even
trying to get it relicensed.

Does having tcg/ be BSD-licensed gain the project anything?
>From my point of view I don't really see it as a cleanly
separable module of code -- it's quite tightly integrated
with the rest of QEMU, including code in accel/tcg which
is variously GPL or LGPL.
