[JDEV] installing the jabber server libs under sparc-solaris-5.7

[Peter Köllner]

i encountered the following problems while installing the jabber server 
libraries on solaris 7 (fetched from jabber.org download path):

install.sh:

on solaris 7, you have to use /usr/xpg4/bin/id instead of standard id to use
id -u to get the user id. check for uname -s = SunOS and uname -r = 5.7.

adns0.7:

the install parameters did not work.
-add AC_PROG_INSTALL to configure.in
-use automake --add-missing to install a copy of install-sh
-for some reason i did not yet find out INSTALL_DATA did not resolve to 
something useful. i replaced them by INSTALL in src/Makefile.in for a quick 
workaround.

libxode-0.9:

compiler complains about incompatible flags -fPIC and -pg
-removed -pg from src/Makefile.am, rerun automake; autoconf; configure

libjabber:

configure did not find libxode due to solaris' strange library path policies.
.configure --with-libxode=/usr/local (must be a better way)

libetherx:
same problem as libjabber: same solution

missing libadns: copied the LIBXODE tests in configure.in and added 
LIBADNS_ADD where LIBXODE_ADD is found. rerun autoconf.
there was another problem with  autoheader and libtool, but i did not yet 
figure out if that was in the original destribution or was caused by all the 
reconfigurations inbetween. it was solved by rewriting acconfig.h with
#undef HAVE_LIBSOCKET
#undef HAVE_SNPRINTF,
rerunning autoheader etc.

then rm ltconfig, ltmain and libtool,  run automake --add-missing and
ln -s /usr/local/bin/libtool to libtool (pew....)

jabber-transport-0.9:
libtool: link: `-L' cannot specify a relative directory
make[2]: *** [jserver] Error 1

this is caused by the definition of
ETHERX_LIBDIR = -L /usr/local/lib in src/Makefile,
which itself can be tracked down to the invocation of etherx-config --libdir
in macros/etherx.m4

a manual start of etherx-config reveals a leading space in the return value.
so etherx-config.in has to be changed so that there is no leading space 
produced, which can be achieved by changing the output="$output blurb" lines
to
addoutput="blurb" and 

if test -z "$output"; then
  output = $addoutput
else
  output = "$output $addoutput"
fi

at the end of the option case switch  

another problem occurs in src/modules, where "if ! test" does not work.
i changed that in src/modules/Makefile.am to "if test !" in two places.
