[Buildroot] [PATCH 2/8] package/rpcbind: include cdefs.h where needed

[Yann E. MORIN <yann.morin.1998@free.fr>]

rpcbind uses a macro defined in sys/cdefs.h but does not included it
explicitly, relying on the glibc behaviour to include it from its own
headers.

Now that we also have a sys/cdefs.h for musl (which completes the triade
glibc/uClibc/musl), sys/cdefs.h is always available.

Fixes:
    http://autobuild.buildroot.org/results/346/346c5b562c244ddb039db2f86f71d670a01ed9ce/
    http://autobuild.buildroot.org/results/d77/d77454265c45539178c008c5d92509c441447675/
    and numerous such autobuild failures

+Subject: [PATCH] src: include cdefs.h for the __P() macro
+
+The __P() macro is defined in cdefs.h, so we must include it explcitly
+rather than relying on it being included by another header.
+
+cdefs.h is a glibc-ism; glibc includes it almost everywhere form its own
+headers. So it automatically gets included for glibc.
+
+However, cdefs.h is not present in musl, so its headers do not include
+it. We must thus include it when we need __P() (of course, one will have
+to provide his own cdefs.h in this case).
