[Bug translator/16276] resource limits interfering with buildrun.cxx make -j

[Masanari Iida]

Hi,
After 3c4476ac7d50 added, I can not compile the systemtap.

  CXX      stap-buildrun.o
buildrun.cxx: In function ‘int run_make_cmd(systemtap_session&,
std::vector<std::basic_string<char> >&, bool, bool)’:
buildrun.cxx:69:61: error: comparison between signed and unsigned
integer expressions [-Werror=sign-compare]
buildrun.cxx:70:61: error: comparison between signed and unsigned
integer expressions [-Werror=sign-compare]
cc1plus: all warnings being treated as errors
make[2]: *** [stap-buildrun.o] Error 1
make[2]: Leaving directory `/home/iida/Repo/systemtap'
make[1]: *** [all-recursive] Error 1
make[1]: Leaving directory `/home/iida/Repo/systemtap'
make: *** [all] Error 2

I am testing this on Fedora 18(x86).

Thanks
Masanari
