-----------------------------------+----------------------------------------
 I have just fixed some problems with the CCT cactus-test VM, but I cannot
 get Cactus to build.  It fails during configuration with
 {{{
 checking host system type... x86_64-unknown-linux-gnu
 checking whether make sets ${MAKE}... yes
 checking whether the C compiler (gcc -g3 -march=native -std=gnu99
 -rdynamic) works... no
 configure: error: installation or configuration problem: C compiler cannot
 create executables (see configs/<configname>/config-data/config.log for
 details).
 }}}

 In config.log, there is
 {{{
 configure:1015: checking whether the C compiler (gcc -g3 -march=native
 -std=gnu99 -rdynamic) works
 configure:1032: gcc -o conftest -g3 -march=native -std=gnu99
 -DMPICH_IGNORE_CXX_SEEK -rdynamic conftest.c  1>&5
 conftest.c:1:0: error: CPU you selected does not support x86-64
 instruction set
 }}}
 I don't understand what is going on here.
 1. Why should gcc insist that the CPU (which is 'native') support 64 bit
 instructions?
 2. Why does this fail when it used to work, the last time this VM was up
 and running?  Did the VM get moved to another host?

 /proc/cpuinfo says
 {{{
 model name      : QEMU Virtual CPU version (cpu64-rhel6)
 }}}

 This was a clean build, with the configs directory wiped before building.
 It uses the simfactory ubuntu.cfg optionlist.  The VM is a standard ET
 build slave running "Ubuntu 12.04.5 LTS".
