If syspath is going to include .../ it isn't a bad idea for
sys.mk to resolve it.
Something like:
.if ${.MAKE.LEVEL} == 0
# just in case -m, MAKESYSPATH or our default has .../
# export a sanitised version...
# first any -m* from command line,
# then any MAKESYSPATH and finally ${.PARSEDIR}
_makesyspath:= ${.MAKEFLAGS:tW:S/ -m / -m/g:tw:M-m*:S,^-m,,} \
${MAKESYSPATH:U} \
${.PARSEDIR}
# replace .../.* with ${.PARSEDIR}, not perfect but pretty close
MAKESYSPATH:= ${_makesyspath:S,:, ,g:C,^\.\.\./.*,${.PARSEDIR},:u:ts:}
.export MAKESYSPATH
.endif
then if a sub-make is launched in a objdir outside of the tree, it will
still find the correct sys.mk etc.
