There are some cases we want the manipulation cross-canadian performance
on TARGET_OS, there are also cases like meta-environment where we do not
want this manipulation.
We did try and use immediate expansion to avoid this problem and it
works in the non multilib case. If we have a multilib that used an
extension, like for example:
require conf/multilib.conf
MULTILIBS = "multilib:lib32 multilib:lib64"
DEFAULTTUNE = "mips32r2"
DEFAULTTUNE_virtclass-multilib-lib32 = "mips64-n32"
DEFAULTTUNE_virtclass-multilib-lib64 = "mips64"
then the n32 extension case will be misconfigured.
It turns out saving an unexpanded variable is hard. The best I could
come up with was:
SAVEDTOS := "${@d.getVar('TARGET_OS', False).replace("{", "*")}"
and then
localdata.setVar("TARGET_OS", d.getVar("SAVEDOS", False).replace('*','{'))
which is rather evil, I'd challenge someone to come up with a nicer way
of making it work though!
Rather than the above madness, we modify cross-canadian to make the
problamtic code conditional.
This fixes the original issue (where a linux-gnuspe target was seeing
'linux') of
http://cgit.openembedded.org/openembedded-core/commit/?id=0038634ee6e2b6035c023a2702547f20f67c103a
but also fixes the multilib one.
