Change the way opt_USE is worked on, so that it is not evaluated too early.

Would a check here and on line 550 be useful to determine if USE_${_u:tu} already contains _u?

For example,

OPT1_USE= ldconfig=${PREFIX}/lib/blah/lib
OPT2_USE= ldconfig=${PREFIX}/lib/blah/lib

results in USE_LDCONFIG containing the same path twice.

Tested this and it results in the same behavior as an empty USE_LDCONFIG= .

Well, in this case, you are asking for it to be put twice.

What you want to do is:

.if ${PORT_OPTIONS:MOPT1} || ${PORT_OPTIONS:MOPT2}
USE_LDCONFIG+= ${PREFIX}/lib/blah/lib
.endif
