Subject: Changed canonical paths to absolute paths in symmake.

Canonical paths were resolving to empty if the paths didn't exist,
which causes problems for clean platform builds. Using absolute paths
instead will generate all required paths.

This will cause a minor inconvenience of warnings about some nonexistent
paths during makefile generation phase of abld builds, but this is
unavoidable. Sbsv2 builds do not display any warnings.
