investigate these iOS build warnings

[jmoody]

xctoolchain/usr/bin/libtool: -dynamic not specified the following flags are invalid: -ObjC

i386/libGHUnitIOSSimulator.a(GTMObjC2Runtime.o) has no symbols
x86_64/libGHUnitIOSSimulator.a(GTMObjC2Runtime.o) has no symbols

i saw these when i was reviving gh-unit and was able to fix them, however i did remove the GTMObjC2Runtime from the sources.

are we still interested in including GTM? last release was in 2011.

we use the GTM code to generate the JUnit style xml reports.

other than that, i am not sure why it is included.

I think we only use it to generate the JUnit xml, other parts are already removed.

I will close this issue. If it's not fixed in the current version please feel free to reopen this issue!
