[MAC80211] Build mac80211 package fail with error: "target pattern contains no '%'. Stop."

[borgchen]

Hi All

I got error while compiling mac80211 package.
this are the error messages that I had:

target pattern contains no '%'. Stop.

and the problem was located in package/kernel/mac80211/Makefile
=>
$(eval $(foreach drv,$(PKG_DRIVERS),$(call KernelPackage,$(drv))))

I think it should be modified to be like:
$(foreach drv,$(PKG_DRIVERS),$(eval $(call KernelPackage,$(drv))))

Which branch? Have you modified the branch? What was your build command?

Many build from the various branches without issue, so I suspect that there is something "different" about what you're doing.

Hi,

I got the same error while compiling the mac80211 package (master branch commit 1bdd3b5f). It probably occurs with an older version of make. The linux distribution I'm currently using to build is quite old, namely Kubuntu LTS 14.04

The make version is GNU Make 3.81

The proposed fix by borgchen solved the issue for me. I think it is a good idea to apply it for the developers using older tools to build the OpenWRT image.

Actually I copied mac80211 folder from master branch to openwrt-18.06 and then found this issue when I compiled openwrt-18.06.
There is no error occurred if I compile master branch directly.
