On some older versions of GNU/Linux, gdbserver now fails to build
due to an undefined reference to NT_ARM_VFP. Same issue on Android,
where this macros is undefined until Android API level 21 (Android
5.0 "Lollipop").
This patch modifies linux-aarch32-low.c to define that macros when
not already defined.
gdb/gdbserver/ChangeLog:
* linux-aarch32-low.c (NT_ARM_VFP): Define if not already defined.
This patch adds a new regs_info regs_info_aarch32 for aarch32, which
can be used by both aarch64 and arm backend.

* configure.srv (srv_tgtobj): Add linux-aarch32-low.o.
* linux-aarch32-low.c: New file.
* linux-aarch32-low.h: New file.
* linux-arm-low.c (arm_fill_gregset): Move it to
linux-aarch32-low.c.
(arm_store_gregset): Likewise.
(arm_fill_vfpregset): Call arm_fill_vfpregset_num
(arm_store_vfpregset): Caa arm_store_vfpregset_num.
(arm_arch_setup): Check if PTRACE_GETREGSET works.
(regs_info): Rename to regs_info_arm.
(arm_regs_info): Return regs_info_aarch32 if
have_ptrace_getregset is 1 and target description is
arm_with_neon or arm_with_vfpv3.
(initialize_low_arch): Don't call init_registers_arm_with_neon.
Call initialize_low_arch_aarch32 instead.
