Tom de Vries 97e9c24c38 [gdb/build] Fix build on postmarketos 
I tried building gdbserver on postmarketos (which is based on alpine linux,
which uses musl libc), and ran into:
...
gdbserver/linux-low.cc: In lambda function:
gdbserver/linux-low.cc:1907:41: error: \
  'W_EXITCODE' was not declared in this scope
 1907 |               mark_lwp_dead (leader_lp, W_EXITCODE (0, 0), true);
      |                                         ^~~~~~~~~~
...

The macro W_EXITCODE is not defined in gdbsupport/gdb_wait.h.

OTOH, WSETEXIT is defined there, but unused:
...
 /* These are not defined in POSIX, but are used by our programs.  */

 #ifndef WSETEXIT
 # ifdef W_EXITCODE
 #define WSETEXIT(w,status) ((w) = W_EXITCODE(status,0))
 # else
 #define WSETEXIT(w,status) ((w) = (0 | ((status) << 8)))
 # endif
 #endif
...

Fix this by dropping the WSETEXIT definition, and instead defining W_EXITCODE.

Tested on x86_64-linux, in combination with an "#undef W_EXITCODE" to make
sure the definition is exercised.
