 There currently isn't.

 I will try to make a patch that adds BR2_HOST_GCC_AT_LEAST_*, but I don't have
the older gcc to test it with. There are three packages that have
BR2_TOOLCHAIN_GCC_AT_LEAST and that also have a host variant:

- nodejs (4.8)
- directfb (4.5), but host-directfb is not used and never has been used
- cmake (4.7), but that's only needed for ctest which needs jsoncpp which
doesn't have a host variant.

 So probably only nodejs will need this, but it would be good to test host-cmake
with gcc 4.6 or earlier. Does anyone have that lying around?

 Regards,
 Arnout
