Package: zlibc
Version: 0.9k-4.1
Currently it fails to build thus:
filetype.c: In function 'zlib_initialise':
filetype.c:167:16: error: 'SYS_open' undeclared (first use in this function)
fd=syscall(SYS_open,"/proc/self/cmdline", O_RDONLY);
^
filetype.c:167:16: note: each undeclared identifier is reported only
once for each function it appears in

SYS_open is a special case of SYS_openat and is no longer provided for
recent architectures such as aarch64. Here is a patch to use SYS_openat
instead when it is available:

if ( fd > 0 ){
cmdline[1024]='\0';
n = read( fd, cmdline,1024 );
It appears to work with that patch.
You could alternatively patch it like this (not tested):
+#ifdef SYS_open
fd=syscall(SYS_open,"/proc/self/cmdline", O_RDONLY);
+#else
+ fd=syscall(SYS_openat, AT_FDCWD, "/proc/self/cmdline", O_RDONLY);
+#endif
