Re: libicudata in non-standard directory linking issues.

to get icu working on Openindiana/Illumos/Solaris ...

http://bugs.icu-project.org/trac/ticket/9390

I downloaded the very latest icu4c from icu-project and then worked
through the source till I compiled it ... :)

I put a patch on their bug system to get it to compile on Solaris ...
although someone would need to check if that actually fixed it for
other platforms.

I do set PATH and LD_LIBRARY_PATH before autogen/configure/gmake ...
this specific batch of commands is especially annoying because it
overrides the default LD_LIBRARY_PATH, rather than setting
'LD_LIBRARY_PATH="$O/lib:$LD_LIBRARY_PATH"' or similar.

yeah, it finds icu-config, but it doesn't appear to do anything with
the output because if I grep for /opt/icu it can't find it.

the only information in config_host.mk related to icu are these 3 lines:
export SYSTEM_GENBRK=/opt/icu/bin/genbrk
export SYSTEM_GENCCODE=/opt/icu/sbin/genccode
export SYSTEM_GENCMN=/opt/icu/sbin/gencmn

I then add extra includes and libs to the SOLARINC,
SOLARINC_FOR_BUILD, SOLARLIB and SOLARLIB_FOR_BUILD defs.
I'm still hoping that I can get a full build of LibreOffice on
OpenIndiana, but I'll still have to wait to see if it works after I
compile it :)
