Set architecture to arm in arm-*.xml files
This patch is to add the following line to various arm target description
xml files,
<architecture>arm</architecture>
in order to fix problems I've seen on aarch64 multi-arch debugging,
detach^M
Detaching from program: build-gdb/gdb/testsuite/gdb.base/attach, process 17145^M
(gdb) PASS: gdb.base/attach.exp: attach1 detach file^M
No executable file now.^M
Architecture of file not recognized.^M
(gdb) FAIL: gdb.base/attach.exp: attach1, purging symbols after detach
Without this patch, struct target_desc *tdesc_* are not initialised
properly, that is, fields arch and osabi in 'struct target_desc' are
not set properly. This doesn't cause any problems on single arch
debugging, because arch-utils.c:gdbarch_info_fill will guess correctly.
However, in multi-arch debugging, gdbarch_info_fill gets the aarch64
arch, but the target description is for arm (because the current
inferior is 32-bit arm).
It is a surprise to me we didn't set architecture to "arm" before in *.xml
files, and I didn't find out why didn't do so. AFAICS,
gdb/features/arm-with-iwmmxt.xml was added firstly (in patch
https://sourceware.org/ml/gdb-patches/2007-01/msg00593.html)
which had <architecture>iwmmxt</architecture>, however, afterwards,
architecture isn't set anymore in features/arm-*.xml files (in patches
https://sourceware.org/ml/gdb-patches/2009-07/msg00689.html and
https://sourceware.org/ml/gdb-patches/2010-08/msg00225.html).
