If I build a port that uses USE_FORTRAN, then the variable ${LDFLAGS}

%cd /usr/ports/math/lapack
%make -V LDFLAGS
-Wl,-rpath=/usr/local/lib/gcc46
%make -V MAKE_ENV
LDFLAGS= -Wl,-rpath=/usr/local/lib/gcc46 ...
I am trying to create a port in which this creates problems.
Where does the extra space at the beginning come from, and how do I get
rid of it?
I solved the mystery. Inside /usr/share/mk/sys.mk is the line:
LDFLAGS ?=
I think that it is a bug in make that
XXX=
XXX+=xxx
results in XXX having the value xxx.
