In preparation for upgrading compilers and build platforms, we would
like to get better separation between the two. At least on Linux and
Solaris this is certainly possible. Some work for this was already done
in Jdk 8 but it was never taken all the way through into actual usage.
In this bug, the configure parameters relating to this will be changed to:
--with-sysroot: Sets a sysroot directory that will be propagated to the
compiler (gcc --sysroot) if supported and which will be used by
configure to look for all dependencies like headers and libraries. (old
--with-sys-root will be kept for compatibility as an alias)
--with-toolchain-path: Prepends to the path when looking for compilers
and other target specific tools. Replaces --with-tools-dir, which will
also be kept for compatibility as an alias.
--with-extra-path: Prepends to the path when looking for everything.
--with-devkit: Points to the root of a devkit. A devkit may have a
"devkit.info" in its root detailing values for the above three
parameters. If not, the fallback behavior is what it used to do. (set
toolchain_path to devkit/bin and some options for subdirs for sysroot)
Along with these changes some more was needed and done:
* To get it to work properly on Solaris, the OPENWIN variables were
removed and replaced with X_LIBS and X_CFLAGS. Several unnecessary
runtime paths for awt* libs were removed and some were added where they
were actually needed instead. All the libs have been verified to still
find their dependencies with ldd.
* The devkit generation makefiles for linux (in root/make/devkit) were
updated to the proposed compiler versions and adding the devkit.info file.
* A minor fix in compare.sh that was missed in an earlier patch.
