There are helper functions in utils.bbclass that take care of multilib datastore
setup, please use them instead of re-implementing what they do. USe
all_multlilib_tune_values() in particular.
Thanks for the reply, but I'm afraid that all_multlilib_tune_values() isn't
suitable for this case, what need to display is something like:
lib32: DEFAULTTUNE = "x86"
lib32: TARGET_SYS = "i686-pokymllib32-linux"
lib32: TUNE_FEATURES = "m32"
But all_multlilib_tune_values() returns all values, e.g:
DEFAULTTUNE = "core2-64 x86"
If there is only one multilib variant, it can work if we remove "core2-64" from
DEFAULTTUNE, then we will get "x86", but if there are multiple multilib
variants, e.g., lib32 and lib64, then
all_multlilib_tune_values(d, 'DEFAULTTUNE') is:
DEFAULTTUNE = "core2-64 x86 <foo>"
We don't know how to strip x86 for lib32, or <foo> for lib64. So I think that
the current implementation is a must.
