Subject: ccache: disable assembler support, it breaks kernel initramfs images
X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=720f8eb18ec1201998734d59bd12e97105bed604;p=openwrt%2Fstaging%2Fadrian.git

ccache: disable assembler support, it breaks kernel initramfs images

The reason is that ccache does not recognize and process the .incbin
directive, so caching is unreliable.
See https://github.com/ccache/ccache/issues/136 for more information.
