Description

adding lib32-libbpf(-dev) to SDK.
But, libbpf package's TARGET_CC_ARCH is always "-m64".
And, after added TOOLCHAIN_TARGET_TASK:append = " lib32-libbpf-dev", it met Error: Unable to find a match: lib32-libbpf-dev.

Steps to Reproduce

1. setup

$ ./wrlinux-x/setup.sh --machines intel-x86-64 --dl-layers
$ . ./environment-setup-x86_64-wrlinuxsdk-linux
$ . ./oe-init-build-env


2. adding multilib and lib32-libbpf
conf/local.conf

+ AVAILTUNES += "x86 x86-64"
+ MULTILIBS = "multilib:lib32"
+ DEFAULTTUNE:virtclass-multilib-lib32 = "x86"
+ IMAGE_INSTALL:append = " lib32-libbpf"
+ TOOLCHAIN_TARGET_TASK:append = " lib32-libbpf-dev"


3. checking TARGET_CC_ARCH
TARGET_CC_ARCH is not "m32"

$ bitbake -e lib32-libbpf | grep "^TARGET_CC_ARCH="
TARGET_CC_ARCH=" -m64 -march=nehalem -mtune=generic -mfpmath=sse -msse4.2 -fstack-protector-strong  -O2 -D_FORTIFY_SOURCE=2 -Wformat -Wformat-security -Werror=format-security"
