[OE-core] [PATCH 5/6 V3] gcc-crosssdk: share work directories

[Robert Yang]

The gcc-crosssdk.inc edited the files of config/*/linux*.h in ${S},
which made the source incompatible. Copy config to config-sdk, and edit
the files in config-sdk, configure will read the files in it when build
gcc-crosssdk.

The sed command for configure is more complicated than for configure.ac,
this is because there is such a line /boot/home/config/ in it, we should
not substitute it.
