The clang compiler on MacOS 10.9 (Maverick) generated a warning when
LDFLAGS where passed on the command line. This change lets the RSB
build RTEMS GCC tools on a clean Maverick install.
On NetBSD with ksh changing into a symlink made PWD the link's
target path so a 'cd ..' returned you to that parent and not
the parent you started from. Record the build top and then
change back to that path.
Change the package names to the actual packages and remove the
extra directory in the build tree. This makes the paths simpler.
Nesting if statements did not correctly process the contents of
the nested if script. This change makes the processing uniform
across all the logic stages.
Python's distutil's copy tree code maintains a cache of directories
created so deleting a tree a different way then coping the same
tree results in an error because the destination folders in the
tree are not present because distutils thinks they exist. The
solution is to implement a copy tree function.
This changes adds support to build the autotools if the host installed
version is not a suitable version. Autoconf and automake have hard coded
references to the install prefix and host tools and this makes it impossible
to relocate, that is use in any path other than the install prefix. To
bootstrap automake you need to first build a suitable autoconf and with that
you can built automake for the install prefix. The other complication is
not referencing the install prefix in the path when building in the RSB.
Having the install prefix in the path can result in strange issues appearing
such as gcc using a new assembler feature not present in an older assember
installed under the install prefix.
The process is to build the autotools using an install prefix to an
internal path inside the RSB temporary path and to use that autoconf
to build the version for the install prefix. The internal install
prefix version is also used to bootstrap RTEMS.
