@subsubheading Overriding @command{configure} test results
Sometimes, it might be necessary to override the result of some
@command{configure} test, for example in order to ease porting to a new
system or work around a bug in a test. The toplevel @command{configure}
script provides three variables for this:
@table @code
@item build_configargs
@cindex @code{build_configargs}
The contents of this variable is passed to all build @command{configure}
scripts.
@item host_configargs
@cindex @code{host_configargs}
The contents of this variable is passed to all host @command{configure}
scripts.
@item target_configargs
@cindex @code{target_configargs}
The contents of this variable is passed to all target @command{configure}
scripts.
@end table
In order to avoid shell and @command{make} quoting issues for complex
overrides, you can pass a setting for @env{CONFIG_SITE} and set
variables in the site file.
