We need fix the path in tclConfig.sh, tdbcConfig.sh and itclConfig.sh
for sstate, otherwise there would be build failures when use the sstate
across different builds.
e.g., when building expect:
[snip]
tmp/sysroots/qemuarma9/usr/include/tcl8.6
checking for Tcl private include files... configure: error: Cannot find private header tclInt.h in
/path/to/another/build/tmp/sysroots/qemuarma9/usr/include/tcl8.6.1
Configure failed.
