If a kernel package was defined where all KCONFIG symbols were dynamic,
and versioned, no FILES would be installed, as the foreach evaluation was
providing the value of the variable defined by the KCONFIG symbol name
including the version test
Fix this by calling the version_filter function on the list of KCONFIG
variable names run through by foreach
Example, kernel 6.1:
KCONFIG:=CONFIG_OLD@lt6.1 CONFIG_NEW@ge6.1
filter-out any KCONFIG settings forced by package:
CONFIG_OLD@lt6.1 CONFIG_NEW@ge6.1
there are dynamic settings, so for each of them,
get the value of the make variable defined by symbol name:
CONFIG_OLD@lt6.1 is not set
CONFIG_NEW@ge6.1 is not set
versus
CONFIG_OLD is not set
CONFIG_NEW=m
test if any of these are m, or y
if yes, install files, otherwise, nothing to install
