[OE-core] [PATCH V2 2/8] populate_sdk_ext.bbclass: install multilib SDKs

[Robert Yang]

Fixed:
MACHINE = "qemux86-64"
require conf/multilib.conf
MULTILIBS = "multilib:lib32"
DEFAULTTUNE_virtclass-multilib-lib32 = "x86"
IMAGE_CLASSES += "testimage"

$ bitbake core-image-minimal -cpopulate_sdk_ext
$ bitbake core-image-minimal -ctestsdkext
[snip]
Testing /buildarea/lyang1/test_po/tmp/work/qemux86_64-poky-linux/core-image-minimal/1.0-r0/testsdkext//tc/environment-setup-x86-pokymllib32-linux
test_cvs (oeqa.sdk.buildcvs.BuildCvsTest) ... FAIL
[snip]

It was failed because no lib32 toolchains.

These fixes include:
* Set SDK_TARGETS correctly
* Return multilib depends in get_ext_sdk_depends()
* Write information to all environment-setup-* scripts.

[YOCTO #10647]
