Crash-utility implemented its own strlcpy(), but for now the latest
glibc has added the strlcpy function to POSIX version(which is derived
from OpenBSD). Eventually this caused the follow compilation error:
# make -j8 lzo
...
gcc -c -g -DX86_64 -DLZO -DGDB_10_2 -g -O2 kernel.c -I./gdb-10.2/bfd -I./gdb-10.2/include
In file included from global_data.c:18:
defs.h:5556:8: error: conflicting types for ‘strlcpy’; have ‘size_t(char *, char *, size_t)’ {aka ‘long unsigned int(char *, char *, long unsigned int)’}

[3] 388ae538ddcb ("hurd: Add strlcpy, strlcat, wcslcpy, wcslcat to libc.abilist")
To fix the current issues, let's declare the strlcpy() as a weak
function, and keep the same parameter types with the latest glibc
function.
