ldlex should use streams

[Andreas Jaeger]

We currently have a discussion on the glibc lists that you cannot just
do fopen a file and then read on it, the file pointer need not be at
the beginning of the file (it seems to be in all current
implementations but you never know).

Therefore I propose the following simple patch to avoid this
situation, I don't see a reason for read in that place.

Ok to commit?  I run make check sucessfully.
