Remove various build host references from packages:
libstdc++
libstdc++-staticdev
gcc-runtime-dbg
The references are removoved by correctly setting various compiler
-fdebug-prefix-map settings. There are two main issues:
The default DEBUG_PREFIX_MAP variable references WORKDIR, however,
gcc sources are in a shared folder (work-shared)/
Additionally, DWARF info seems to store symlink names but gcc
seems to resolve symlink names referenced in -fdebug-prefix-map.
