I don't think it'll be a problem.

If you watch what GNU Radio installs, the parts that matter at
runtime are the shared libraries and the python code.

They end up in 

  ${prefix}/lib/libgnuradio-core.so
  ${prefix}/lib/libusrp.so
  ${prefix}/lib/python/site-packages/

FYI, under GNU/Linux, you can check the run-time dependencies of a
shared library by using the ldd command.  E.g.,

  $ ldd /usr/local/lib/libgnuradio-core.so
        linux-gate.so.1 =>  (0xffffe000)
        librt.so.1 => /lib/librt.so.1 (0xb7de7000)
        libfftw3f.so.3 => /usr/local/lib/libfftw3f.so.3 (0xb7d05000)
        libstdc++.so.6 => /usr/lib/libstdc++.so.6 (0xb7c25000)
        libm.so.6 => /lib/libm.so.6 (0xb7c00000)
        libc.so.6 => /lib/libc.so.6 (0xb7adf000)
        libgcc_s.so.1 => /lib/libgcc_s.so.1 (0xb7ad4000)
        libpthread.so.0 => /lib/libpthread.so.0 (0xb7ac0000)
        /lib/ld-linux.so.2 (0x80000000)


You don't need the include files, etc at run time.
