 gcl: Do not override the deployment target

 The build system sets MACOSX_DEPLOYMENT_TARGET to 10.2. This was done
 when Mac support was originally added back in July 2003:

 http://git.savannah.gnu.org/cgit/gcl.git/commit/?id=b54cbfe43d04f84c53c6e211a763b8e02185f4fc

 At that time the current version of Mac OS X was 10.2 and the default
 value of MACOSX_DEPLOYMENT_TARGET was 10.1, which was apparently too
 old for gcl so they changed it to 10.2.

 Meanwhile, macOS Mojave does not support deployment targets that old so
 I've removed this setting from the build system to allow the value set
 by MacPorts (which matches the macOS version) to be used.

 The build fails if the deployment target is 10.6 or later, which I fixed
 by adding -fno-pie to CFLAGS and LDFLAGS, per a suggestion I found in a
 ticket with a similar error message about emacs.

 Closes: https://trac.macports.org/ticket/57312

 The build system also overrides the compiler, for reasons which appear
 no longer to be relevant. We already had a patch to remove this override
 on Intel. I've expanded that patch to include PowerPC.

 Also disable the universal variant because it fails to configure.

 Also prevent building while the port is active due to a different value
 being detected for EMACS_DEFAULT_EL at configure time if the port is
 already active, resulting in a destroot failure.
