<pre>With the change in <a href="http://reviews.llvm.org/D19928">http://reviews.llvm.org/D19928</a>, linking FreeBSD/mips64 libc
fails with:
Assertion failed: ((!this->Sec || this->Sec == Sec) && "multiple .eh_frame
sections not supported for .eh_frame_hdr"), function assignEhFrame, file
../tools/lld/ELF/OutputSections.cpp, line 850.
