Currently, the relocate-sdk.sh script scans the whole extracted SDK tree
to find instances of paths it needs to replace, which can take a
significant amount of time when the SDK is large, particularly relative
to the number of files that actually need to change.
However, the resulting list only depends on the SDK tarball itself, so
we can calculate it at build time and ship it with the tarball so
relocate-sdk.sh can use it directly.
Testing this on my machine with somewhat IOPS-limited rotating media,
the time goes down from:
$ time ./relocate-sdk.sh
Relocating the buildroot SDK from [...] to [...] ...
./relocate-sdk.sh 5.19s user 26.21s system 9% cpu 5:34.40 total
To:
$ time ./relocate-sdk.sh
Relocating the buildroot SDK from [...] to [...] ...
./relocate-sdk.sh 0.49s user 0.29s system 103% cpu 0.749 total

Currently, relocate-sdk.sh must be run _after_ relocating the SDK. There
are cases where it is useful to already prepare the SDK _before_
relocating. For example, it allows to prepare a tarball that the user
has to extract to a specific, pre-defined location and nothing more than
that, which is simpler for the user than requiring the script to be run.
In addition, it hides the build directory that was used by the SDK
builder (somewhat).
Add an optional argument to relocate-sdk.sh that gives the target
directory.

The normal shell does not support the bashism "< <(...)". Therefore
we use a normal pipe to find files containing a specific string.

It will install the script "relocate-sdk.sh" in the HOST_DIR
allowing to adjust the path to the SDK directory in all text
files after it has been moved to a new location.

[Thomas:
- Fix shebang to be /bin/sh instead of /bin/bash, suggested by Arnout
- Use | instead of \ as a separator for sed expressions, suggested by
Arnout, discussed with Wolfgang and others
- Remove ./ at the beginning of LOCFILE, suggested by Arnout
- Fix comment about the path check being made before doing the
replacement, suggested by Arnout
- Fix indentation, suggested by Arnout.]
