> Log message:
> move configure_assembler, configure_c_compiler, configure_linker
> from Unix.common to cm3cfg.common
>
> introduce new function: configure_system_libs
>
> The idea is:
> any code like 'if SYSTEM_LIBS contains "OPENGL"'
> (or checking SYSTEM_LIBORDER, if that is possible/done)
>
> should first call configure_system_libs
> by default configure_system_libs does nothing
>
> However on I386_SOLARIS for example, configure_system_libs
> is a theoretically slow probe to see if OPENGL is present,
> and if so, it adds OPENGL to SYSTEM_LIBS.
>
> We could just always do this check and add to SYSTEM_LIBS
> ahead of time, but it seems expensive.
>
> We could also probably do a more efficient check
> just around file existance. However the way I have written
> the probe is nicely ignorant of the precise files.
> In particular ld -lfoo -o /dev/null succeeds if libfoo is found
> and fails otherwise. That is how the probe works.
>
> We could maybe change my mind about cminstall, but no, not yet at least.
>
> To make this more efficient, we might instead offer:
> proc configure_system_lib(name)
>
> This is both a bit of a breaking change and a bit experimental
> or needs more discussion. However the level at which it
> is breaking miniscule -- it is only current relevant
> for I386_SOLARIS.
>
> I have to look again: I didn't see the Mesa stuff on 2.9/x86/Solaris.
> If it is there, we can probe alternative for it as well.
> Currently we'll just skip the opengl package on Solaris 2.9 x86.
