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

older verisons of glibc would build dl-sysdep as shared-only and dl-support as
yann@1625
     2
static-only.  alpha hooks in a cache variable via dl-auxv.h.  newer versions of
yann@1625
     3
glibc build dl-sysdep as both shared and static which means we now have symbol
yann@1625
     4
duplication for static builds with dl-sysdep and dl-support.  since dl-sysdep
yann@1625
     5
is both shared/static, there is no point in hooking dl-support anymore, so we
yann@1625
     6
can punt it.
