[Dovecot] configure change for 1.0.beta8

[Tomi Vainio]

Hi,

I'm trying to compile dovecot under Solaris 10 with native Mysql
support.  Couple changes are needed before configure can detect and
compile mysql support.  Native Solaris Mysql is installed under
/usr/sfw directory.  Configure can't find libraries and when these are
found -R runtime path is needed for linking.  Also if library name is
given before library path it can't find it.

These changes are needed for configure script
line 29533
for i in /usr /usr/local /usr/local/mysql /usr/sfw; do

line 29548
LIBS="$LIBS -L$MYSQL_LIBDIR -R$MYSQL_LIBDIR"

line 29559
LIBS="$LIBS -lmysqlclient"

line 29770
SQL_LIBS="$SQL_LIBS -L$MYSQL_LIBDIR -R$MYSQL_LIBDIR"

line 29780
LIBS="$LIBS -lmysqlclient"
