Build fail on RELENG_7

[Evan Clarke]

Last night I csup'd to RELENG_7, and have not been able to build it
successfully.

This is running on a VMWare VM.  It keeps on getting memory alloc
fails at the same place each time.  I have increased the VM's RAM from
256MB to 512MB and then to 800 and something.  The physical machine
has 2GB of RAM.

I am doing a make buildworld (with no -j option)

$ /sbin/sysctl hw | grep mem
hw.physmem: 875991040
hw.usermem: 857661440
hw.realmem: 889192448

Build is done in single-user mode with swap enabled.
Here is the failing command (full log available upon request)
