The LD ?= should only define LD as gcc if it is not set within
the makefile (which it isn't in the provided makefile engine example),
?= works only for _undefined_ variables, but $(origin LD) says that LD
is _default_ one.
but if that breaks compatibility in someway that the $origin doesn't...
it's ok by me :)
Looks weird but I didn't investigate.
Looks like LD is a special variable set by [g]make.
Btw, could be useful to have a variable defined to the c++ lib depending on the
gcc version, to add to LIBS in the makefile.
Yes, that is the persistent headache with this stdc++ difference between
gcc4 and gcc2 builds. Some time ago I tried this but failed to propagate
this variable "back" to calling makefile. ;-) I just knew nothing about
two-ways makefiles processing and difference between immediate and
deferred assignments. ;-D Looks like I shoud try again some time.
