Change suggestion how to set MAKESYSPATH as broken incremental build

workaround. Magic ".../share/mk" (search directories up to /)
does not work for f.e. /usr/src/gnu/lib/libgcc because the path
inside is starting from /usr/obj hierarchy and ends up in
/usr/share/mk, not in the /usr/src/share/mk where src.opts.mk is.
IMHO proper fixing of incremental build is needed urgently.

Although this has survived make universe and some upgrade scenarios,
other upgrade scenarios may have broken. At least one form of
temporary breakage was fixed with MAKESYSPATH settings for buildworld
