Does not build

[joshudson]

joshua@nova:~/includeos/hello/upstream/hello_world$ conan install ../hello_world -r includeos -pr gcc-7.3.0-linux-x86_64
ERROR: Error reading 'gcc-7.3.0-linux-x86_64' profile: ConfigParser: Unrecognized field 'build_requires'

I have no idea how to attack this problem. I can see [build_requires] in conanfile.txt and have no idea what conan is upset about.

Trying the clang profile doesn't do any better.
