The file configure.ac checks if jimtcl submodule is present by
looking for the file jimtcl/configure.ac .
But jimtcl has switched to its own build system in 2011 and thus
dropped configure.ac . This cause a build issue on OpenOCD that
was incorrectly fixed by adding a dummy configure.ac in jimtcl.
Fix OpenOCD configure.ac to look for the correct file
jimtcl/configure .
After this fix, another fix would be proposed to jimtcl to drop
its useless dummy file configure.ac .

This patch fixes two corner-cases of finding RTT control block.
The first one is when there was a partial match (even single byte) at
the end of loaded buffer (uint8_t buf[1024]), but this was not part of
full match. In that case `cb_offset` was not updated correctly and the
returned `*address` was lower by the legth of the partial match. In case
of searched 'SEGGER RTT' (the default control block ID) string, it was
enough to match `buf[1023] == 'S'`, which is quite likely to happen, and
the `*address` was offset by 1 (e.g. it was 0x20000fff instead of
0x20010000).
Updating (or even maintaining) `cb_offset` is not needed, as start
address of control block can be calculated based on memory address that
was loaded into `uint8_t buf[1024]`, the offset within this buffer and
the length of expected string.
The second issue is when control block is prepended with a byte that
matches first ID character, e.g. there is `SEGGER RTT` control block ID
is prepended by another `S`, making memory contents be `SSEGGER RTT`. In
that case there was no match found.
Fix that issue by making sure that tested byte is always compared with
first byte of expected control block ID.
While at it, change names of local variables to better describe their
meaning.

- only handles 32 bits PC;
- output file created and left empty on error.

This causes an issue if the system is irresponsive and the examine
