After the Solaris vtv port was added my build of the x86 gcc with x32
support fails.  The build is special since the kernel doesn't have x32
support and I cannot directly run x32 binaries (they are run in a kvm
kernel).  This is used to work well by configuring the tree with
--build and --host etc.

The changes to libvtv/configure.ac forced the execution of some code
for all targets, specifically the AC_USE_SYSTEM_EXTENSIONS macro.
Once I take this (and the code depending on it) out the build is once
again fine.  Below is the change I used.  Can we revert the change
until the Solaris port is correctly done?

What part of this requires bits to run? I see AC_COMPILE_IFELSE, butnot anything which obviously requires running the resulting code.
