This was already fixed for 10.1, I just need to do some docs.

no longer builds on aarch64 (native build) after updating to glibc-2.33. 
http://www-look-4.com/services/usb-type-a/

Due to a glibc 2.33 header file change, the file
http://the-hunters.org/category/computers/
nat/aarch64-linux-hw-point.c no longer builds on OSes using this version of
glibc.

An enum for PTRACE_SYSEMU is now provided by <sys/ptrace.h>.  In the 
past, PTRACE_SYSEMU was defined only in <asm/ptrace.h>.  This is
http://www.iu-bloomington.com/property/properties-in-turkey/
what it looks like...

In <asm/ptrace.h>: https://waytowhatsnext.com/crypto/cryptocurrency-taxes/

#define PTRACE_SYSEMU             31
http://www.wearelondonmade.com/health/check-ups/

In <sys/ptrace.h>:
http://www.jopspeech.com/services/surface-duo/
enum __ptrace_request
{ http://joerg.li/services/kia-rio-price/
  ...
  PTRACE_SYSEMU = 31,  
#define PT_SYSEMU PTRACE_SYSEMU

  ... http://connstr.net/services/mobile-games/
}

When <asm/ptrace.h> and <sys/ptrace.h> are both included in a source
http://fishingnewsletters.co.uk/category/computers/
file, we run into the following build problem when the former is
included before the latter: http://embermanchester.uk/tech/google-drive/

In file included from nat/aarch64-linux-hw-point.c:26:
http://www.go-mk-websites.co.uk/category/computers/
/usr/include/sys/ptrace.h:86:3: error: expected identifier before numeric
constant
   86 |   PTRACE_SYSEMU = 31,
http://www.slipstone.co.uk/technology/cars-interior/
      |   ^~~~~~~~~~~~~

(There are more errors after this one too.)
http://www.logoarts.co.uk/technology/robot-vacuums/
The file builds without error when <asm/ptrace.h> is included after
http://www.mconstantine.co.uk/category/computers/
<sys/ptrace.h>.  I found that this is already done in
http://www.acpirateradio.co.uk/health/transportation-security/ 
nat/aarch64-sve-linux-ptrace.h (which is included by
nat/aarch64-linux-ptrace.c).
