Building QEMU fails with perl regex error

[lukenels]

When building qemu with make after ./configure-arch, the following error happens.

Unescaped left brace in regex is illegal here in regex; marked by <-- HERE in m/^\@strong{ <-- HERE (.*)}$/ at /home/lukenels/src/opensgx/qemu/scripts/texi2pod.pl line 320.
Makefile:463: recipe for target 'qemu.1' failed
make: *** [qemu.1] Error 255

Here is some random system information if it helps:
