[PATCH] gdbserver: ARM: add support for uclinux

[Will Deacon]

When debugging a uclinux target, it is necessary to retrieve the text
and data offsets of the running program in order for symbol resolution
to work correctly.

This patch defines PT_{TEXT,DATA,TEXT_END}_ADDR for ARM, which can be
issued as `magic' addresses to the PTRACE_PEEKUSER request in order to
retrieve the child offsets.

	* linux-low.c: Define PT_TEXT_ADDR, PT_TEXT_END_ADDR and
	PT_DATA_ADDR for ARM targets.
