Deal with bmake-20170301 no longer resolving -C like it used to.

Browse Source 
Several checks assume .CURDIR is resolved, such as for determining RELDIR from
SRCTOP/.CURDIR.  If -C is used then the path is no longer resolved like it was
before which is problematic for symlinked source trees.  A similar change was
also made to ports post bmake-20170301.

This fixes 'make -C <symlinked path> buildworld' using the wrong OBJDIR.

# bmake-20170301 started taking '-C' "as is" for some cases, notably absolute
# paths. Some later comparisons will assume .CURDIR is resolved and matches
# what we would get with 'cd'. So just force resolve it now if it is an
# absolute path.
