rtems.git build broken(?) for --enable-rtemsbsp=psim with samples: multiple definition of `_POSIX_Once_Lock'

[Nick Withers]

Hullo all,

It seems perhaps the rtems.git build is broken for the "psim" BSP, with
samples enabled (at least "hello"): multiple definitions of "_POSIX_Once_Lock".

It builds for the "mvme3100" BSP without error with or without samples

Last little bit from the "make" ("gmake" on my FreeBSD 9.2-PRERELEASE,
r254324, host) output:
