[Ohrrpgce] Can't compile 64-bit hspeak on the nightly build vm

Wed Dec 20 02:35:31 PST 2017

Bah. I wasn't expecting that to work. fbc apparently only does a PIC build
when building a dynamic library, not when building an executable. I think
what's going on here is that fbc calls ld directly, while linkgcc=1 uses
gcc to indirectly call the linker. I guess it's gcc itself which is telling
ld to do a PIE build. I want to fix linkgcc=1.

So could you please try editing SConscript to replace
CXXLINKFLAGS = []
with
CXXLINKFLAGS = ["-no-pie"]
and see if that works (running just plain "scons")
