[rfc][34/37] Eliminate builtin_type_ macros: Use target arch in procfs.c

[uweigand at de dot ibm dot com]

Hello,

procfs.c uses gdbarch_address_to_pointer to convert a target address
into a host address to be passed to the OS when setting watchpoints.

This patch changes procfs_address_to_host_pointer to use the per-target
architecture and its associated pointer types to perform that conversion.
It also removes and unnecessary reference to builtin_type_void_data_ptr
in procfs_auxv_parse.

Bye,
Ulrich


ChangeLog:

	* procfs.c (procfs_address_to_host_pointer): Use target_gdbarch
	and its associated types to perform pointer conversion.
	(procfs_can_use_hw_breakpoint): Likewise.
	(procfs_auxv_parse): Remove unused variable.
