from upstream:

Fix elf/sotruss-lib format-truncation error.

^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Pids from getpid cannot actually be negative, but the compiler doesn't
know this. Other places in this file use (signed) long int for
printing, so this patch makes this place do so as well. Then it
increases the buffer size by one byte to allow for the minus sign that
can't actually occur. It doesn't seem worth using diagnostic pragmas
to save one byte; other place in this file just use a cruder 3 *
sizeof (pid_t) calculation for number of digits.
Tested with GCC mainline with compilation for aarch64 with
build-many-glibcs.py, and with glibc testsuite for x86_64 (built with
GCC 6).
* elf/sotruss-lib.c (init): Increase space allocated for pid by
one byte. Print it with %ld, cast to long int.
