Not all libc implementations define ssize_t as part of stdio.h like
glibc does since the standard only requires this type to be defined by
unistd.h and sys/types.h. For this reason the perf build is currently
broken for toolchains based on uClibc, for instance.
Include sys/types.h explicitly to fix that.
Committer notes:
In addition, in the past this worked in uClibc test systems as there was
another way to get to sys/types.h that got removed in that cset:
tools/perf/util/trace-event.h
/usr/include/traceevent/event_parse.h # This got removed from util/trace-event.h in 378ef0f5d9
/usr/include/regex.h
/usr/include/sys/types.h
typedef __ssize_t ssize_t;
So the size_t that is used in tools/perf/util/trace-event.h was being
obtained indirectly, by chance.
Fixes: 378ef0f5d9 ("perf build: Use libtraceevent from the system")

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
