With the set of libphobos Solaris patches just posted, it would become
possible to enable libphobos on Solaris 11/x86 by default.
This is what this patch does.
* It uses a LIBPHOBOS_SUPPORTED variable both in toplevel configure and
libphobos/configure.tgt, following what libvtv does.
* It's necessary to disable libphobos when Solaris as is in use: it has
a relatively low line length limit of 10240 which is exceeded in a few
libphobos files.
Bootstrapped without regressions on i386-pc-solaris2.11 (as and gas, gas
and gld, Solaris 11.3/11.4/11.5) on top of the previous set of patches.
Also tested manually that explicit
--enable-libphobos/--disable-libphobos give the desired results
(i.e. override the defaults).

toplevel:
* configure.ac (enable_libphobos): Check LIBPHOBOS_SUPPORTED.
* configure: Regenerate.
libphobos:
* configure.tgt (LIBPHOBOS_SUPPORTED): Default to no.
Set to yes explicitly.
(x86_64-*-solaris2.11* | i?86-*-solaris2.11*): Mark supported.
* configure.ac (x86_64-*-solaris2.* | i?86-*-solaris2.*): Only
mark supported with gas.
(ENABLE_LIBPHOBOS): New conditional.
* configure: Regenerate.
* Makefile.am (SUBDIRS): Only set if ENABLE_LIBPHOBOS.
* Makefile.in: Regenerate.
