pkg-infra: assign BR_NO_CHECK_HASH_FOR so it is recursively-expanded
Currently, assigning to BR_NO_CHECK_HASH_FOR but referencing variable
assigned to later, fails. Here's a failing test-case, which is the
reduced test-case of how we handle BR_NO_CHECK_HASH_FOR for now (warning
added for test-case):
export BR_NO_CHECK_HASH_FOR
BR_NO_CHECK_HASH_FOR += $(XENOMAI_SOURCE)
XENOMAI_VERSION = 2.6.4
XENOMAI_SOURCE = xenomai-$(XENOMAI_VERSION).tar.bz2
$(warning BR_NO_CHECK_HASH_FOR='$(BR_NO_CHECK_HASH_FOR)')
all:
Run it with simply make:
$ make
BR_NO_CHECK_HASH_FOR=' '
Now, change the first line to read:
export BR_NO_CHECK_HASH_FOR =
And we now get:
$ make
BR_NO_CHECK_HASH_FOR=' xenomai-2.6.4.tar.bz2'
This new behaviour will be needed later for Xenomai, which handles the
version string in an unusual way, so we can exclude its custom versions.
