configure: add possibility to set arbitrary variable in check_for
If check_for is able to find the required prog/inc/lib, allow it to set an arbitrary variable to 'y'. This variable is then pushed down to the kconfig definition. For example: has_or_abort prog=foobar kconfig=has_foobar If foobar is available, it yields a kconfig variable defaulting to y: config CONFIGURE_has_foobar bool default y If foobar is missing, it yields a kconfig variable defaulting to n: config CONFIGURE_has_foobar bool Thus it is possible to depends on that variabel to show/hide options: config SOME_FEATURE bool prompt "Some feature" depends on CONFIGURE_has_foobar Signed-off-by: "Yann E. MORIN" <yann.morin.1998@anciens.enib.fr>
