    [gdb/tdep] Support catch syscall pipe2 for i386
   =20
    With test-case gdb.base/catch-syscall.exp and target board unix/-m32, w=
e run
    into:
    ...
    (gdb) catch syscall pipe2^M
    Unknown syscall name 'pipe2'.^M
    (gdb) FAIL: gdb.base/catch-syscall.exp: determine pipe syscall: catch s=
yscall pipe2
    ...
   =20
    Fix this by:
    - adding a pipe2 entry in gdb/syscalls/i386-linux.xml.in, and
    - regenerating gdb/syscalls/i386-linux.xml using
      "xsltproc --output i386-linux.xml apply-defaults.xsl i386-linux.xml.i=
n".
   =20
    Tested on x86_64-linux with native and unix/-m32.
