configure looking for prelink

[Claudio Fontana]

Hello all,

I noticed that wine's configure script looks for prelink using

AC_PATH_PROG(PRELINK, prelink, false, [/sbin /usr/sbin $PATH])

I'd suggest changing it to

AC_PATH_PROG(PRELINK, prelink, false, [/sbin /usr/sbin /usr/local/sbin $PATH])

to cover the case where the prelink package is built from source and
installed in the default prefix (/usr/local).

Thanks,

Claudio Fontana
