Joel Carlson 8fed162987 core/sdk: don't mangle symlinks with '.' or '..' at start
The current transform changes any '.' at the start of a filename to
$(BR2_SDK_PREFIX). This also applies to the target of a symlink, when
it is relative.

We thus might end up with something like:
    $(BR2_SDK_PREFIX)/bin/aarch64-linux-gnu-ar ->
    $(BR2_SDK_PREFIX)./opt/ext-toolchain/bin/aarch64-linux-gnu-ar

when it should be:
    $(BR2_SDK_PREFIX)/bin/aarch64-linux-gnu-ar ->
    ../opt/ext-toolchain/bin/aarch64-linux-gnu-ar

We fix that by making sure we always remove a known prefix, i.e. we
remove the path to host dir. The obvious solution would be to cd into
$(HOST_DIR)/.. , then tar ./host/ and finally use a --transfrom pattern
as 's,^\./$(notdir $(HOST_DIR)),$(BR2_SDK_PREFIX)'.

Since $(HOST_DIR) can point to a user-supplied location, we don't know
very well how the pattern may patch.

Instead, we cd into / and tar the full path to $(HOST_DIR).

Since tar removes any leading '/', it would spurr a warning message,
which is annoying. So we explicitly remove the leading '/' from
$(HOST_DIR) when we tar it.

Finally, we transform all filenames to replace a leading $(HOST_DIR)
(without a leading /) to the prefix to use.

  - use a single transform pattern
  - use full HOST_DIR path as pattern to replace
  - update commit log accordingly

README

Buildroot is a simple, efficient and easy-to-use tool to generate embedded
Linux systems through cross-compilation.

The documentation can be found in docs/manual. You can generate a text
document with 'make manual-text' and read output/docs/manual/manual.text.
Online documentation can be found at http://buildroot.org/docs.html

To build and use the buildroot stuff, do the following:

1) run 'make menuconfig'
2) select the target architecture and the packages you wish to compile
3) run 'make'
4) wait while it compiles
5) find the kernel, bootloader, root filesystem, etc. in output/images

You do not need to be root to build or run buildroot.  Have fun!

Buildroot comes with a basic configuration for a number of boards. Run
'make list-defconfigs' to view the list of provided configurations.

Please feed suggestions, bug reports, insults, and bribes back to the
buildroot mailing list: buildroot@buildroot.org
You can also find us on #buildroot on Freenode IRC.
