Patch file

I'm not sure why it is included in the logic to determine which version of =
GCC
is used. But it sometimes causes unexpected result in non-cleanroom
environment.

Let me assume following situation.

* I'm user of portmaster.
* On my FreeBSD system some ports that use 'USE_GCC=3Dyes' are installed.
* I'd like to change default version of GCC from 11 to 12.

To achieve my purpose I take following steps.

1. Add 'DEFAULT_VERSIONS+=3Dgcc=3D12' to /etc/make.conf
2. Execute `portmaster "$(pkg info -r gcc11 | grep -v ':$')"`

After finishing them, it is expected that gcc12 is installed and all packag=
es
that depended on gcc11 now depend on it. But what really happens is that gc=
c12
isn't installed and dependency doesn't change at all.

It is because Mk/bsd.gcc.mk checks if specific version requested is already
installed and installed gcc11 package is detected and used. But obviously it
conflicts with the result user usually expects when he sets DEFAULT_VERSION=
S in
/etc/make.conf.

So change the logic so it doesn't check installed version of GCC at all.
