Bug#656182: vsftpd FTBFS on alpha: No getpid syscall on Alpha Linux!

Source: vsftpd
Version: 2.3.5-1
Severity: important
Tags: patch

Justification: Fails to build from source (but built in the past)

vsftpd FTBFS on Alpha.  From the build log:

gcc -c sysdeputil.c -g -O2 -Wformat -Wformat-security
-Werror=format-security -W -Wshadow -idirafter dummyinc
sysdeputil.c: In function 'vsf_sysutil_getpid_nocache':
sysdeputil.c:1371:18: error: '__NR_getpid' undeclared (first use in this
function)

This occurs because the syscall is getxpid, not getpid, on Alpha Linux.

The fix is:
