Failed to build rescue with gcc 4.9

[Craig Rodrigues]

Hi,

The build host VM that I used was FreeBSD 10.1-RELEASE, amd64.

I took this patch for libc++ and applied it to my tree:

http://reviews.llvm.org/D8461

I used this script to build with gcc 4.9:

https://github.com/freebsd/freebsd-ci/blob/master/scripts/build/cross-build.sh

Building rescue failed.  You can see the full build log here:

The relevant section seems to be this:

I double checked.  cat.lo is not a truncated file.
# ls -l cat.lo ; file cat.lo
-rw-r--r--  1 jenkins  wheel  13112 Mar 28 21:17 cat.lo
cat.lo: ELF 64-bit LSB relocatable, x86-64, version 1 (FreeBSD), stripped

Any ideas?
