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

[Joel Sherrill]

Hi

Haven't tested this beyond noting that the build continues.
Please let us know if this works.

$ git diff src/once.c
diff --git a/cpukit/posix/src/once.c b/cpukit/posix/src/once.c
