Reasons
This warning may be displayed if EMAKEFLAGS is defined with options that contain spaces in the value (for example, --emake-option="value with spaces"). Depending on how you use EMAKEFLAGS, this may result in builds not operating correctly. Specifically, if you specified --emake-root or --emake-resource via EMAKEFLAGS, and those options have spaces, your build may not use the correct root or the correct resource.
Fixes
For the issue mentioned above, use the EMAKE_ROOT environment variable to specify the emake root, and eliminate spaces in your resource specification.
