[YOCTO #6951]

The TOOLCHAIN_CONFIGSITE_SYSROOTCACHE value was defaulting to the nativesdk
path and not the associated target path.  Set the value in toolchain-scripts
to the target path.

Be sure to set the MLPREFIX within the meta-environment script as multilibs
are processed.

Update the config_site file name to use -BPN- not PN.  Otherwise the
environment processing can't find the correct filename.

Some time ago, the sstate name field was dropped. This code wouldn't have
worked since then. Makes me wonder if we really need it.

Anyhow, my last patch properly breaks it. This fixes the naming so
it works as designed again.

This ensures consistent build results and avoids build failures when compiler flags
change for example.

Using "1" with getVar is bad coding style and "True" is preferred.
This patch is a sed over the meta directory of the form:

sed \
 -e 's:\(\.getVar([^,()]*, \)1 *):\1True):g' \
 -e 's:\(\.getVarFlag([^,()]*, [^,()]*, \)1 *):\1True):g' \
 -i `grep -ril getVar *`

This is the result of running the following over the metadata:

sed \
-e 's:bb.data.\(setVar([^,()]*,[^,()]*\), *\([^ )]*\) *):\2.\1):g' \
-e 's:bb.data.\(setVarFlag([^,()]*,[^,()]*,[^,()]*\), *\([^) ]*\) *):\2.\1):g' \
-e 's:bb.data.\(getVar([^,()]*\), *\([^(), ]*\) *,\([^)]*\)):\2.\1,\3):g' \
-e 's:bb.data.\(getVarFlag([^,()]*,[^,()]*\), *\([^(), ]*\) *,\([^)]*\)):\2.\1,\3):g' \
-e 's:bb.data.\(getVarFlag([^,()]*,[^,()]*\), *\([^() ]*\) *):\2.\1):g' \
-e 's:bb.data.\(getVar([^,()]*\), *\([^) ]*\) *):\2.\1):g' \
-i `grep -ril bb.data *`

This commit changes the sysroots path to be machine specific.

Changes includes:

1) STAGING_DIR_TARGET and STRAGING_DIR_HOST points to machine specific
paths.

2) task stamp files. Adding ${MACHINE} info into stamp files for
do_populate_sysroots and do_package tasks. Add a BB_STAMPTASK_BLACKLIST
to keep native, nativesdk, crosssdk, and cross-canadian stamp unchanged.

3) siteconfig path. Separate the site config path for different machines
to avoid one machine adopting the cache file of another machine.

4) sstate. Add machine name to sstate manifest file.
Change relocation code for sstate paths since sysroot is machine.
Keep native, nativesdk, crosssdk, and cross-canadian unchanged.

5) toolchain scripts. Change the environment path to point to machine
specific sysroots in toolchain scripts bbclass.

6) Relocate la files when populating to a different machine of the same
architecture.

7) Exclude STAGING_DIR_TARGET and STAGING_DIR_HOST parameter from sstate
siginfo since they contain ${MACHINE} information.

Original we used absolute path in sysroot-destdir for both native and
target recipes. This commit changes target recipes to use relative path
which is same as the image directory.

[BUGID #379]

In a strange configuration, siteconfig could have already generated it's
directory, but decided it needs to regenerate the site config.  The lack
of -p in the mkdir causes a failure.

siteconfig: use SITECONFIG_SYSROOTCACHE and use sstate-interceptfuncs

Use the new sstate-interceptfuncs functionality to interpose do_siteconfig
between the sstate_install and package.
