In this example, glibc itself as well as everything that leads to
Coreutils in the dependency graph is rebuilt.
+@item --with-configure-flag=@var{package}=@var{configure-flag}
+Add @var{configure-flag} to the list of configure-flags applied to
+the arguments of @var{package}, where @var{package} is a spec such as
+@code{guile@@3.1} or @code{glibc}. The build system of @var{package}
+must support the argument @code{#:configure-flags}.
+
+For example, the command below builds GNU Hello with the
+configure-flag @code{--disable-nls}:
+
+@example
+guix build hello --with-configure-flag=hello=--disable-nls
+@end example
+
+@quotation Warning
+Currently, there is a primitive check for whether the build system
+supports the argument @code{#:configure-flags} or not, however
+users should not rely on it.
+@end quotation
