Please use a faked git-describe string: 2022-08-30-g68683d3811a8

For stuff like that I prefer:

LIBCAMERA_IPAS-y				:=
LIBCAMERA_IPAS-$(PTXCONF_LIBCAMERA_IPA_IPU3)	+= ipu3
...

I'd do this as part of the LIBCAMERA_CONF_OPT. Then yoy can reuse the
variable below.

Use 'n' as the last argument. And this should have a comment, why this
library is not stripped.

Break all four lines before the filename.

	@$(foreach ipa,$(LIBCAMERA_IPAS-y), \
		$(call install_ipa, $(ipa), $(ipa))$(ptx/nl))

Untested, instead of the stuff above.
