Subject: [PATCH] Include unistd.h for ssize_t
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

When compiling on buildroot I get:
`src/tls.c:235:28: error: ‘ssize_t’ undeclared (first use in this
function); did you mean ‘size_t’? `

To have this POSIX type available we will need to include
`sys/types.h` or `unistd.h`.
