package/rpcbind: fix musl build
rpcbind uses the __P() macro defined in sys/cdefs.h but does not includes it explicitly, relying on the glibc behaviour to include it from its own headers. But this macro does nothing but expands as its argument. In the past, it did provide support for pre-ANSI compilers that did not support function prototypes. Those are now gone, and glibc provides this macro for legacy code. Patch out the use of __P() altogether. Fixes: http://autobuild.buildroot.org/results/346/346c5b562c244ddb039db2f86f71d670a01ed9ce/ http://autobuild.buildroot.org/results/d77/d77454265c45539178c008c5d92509c441447675/ and numerous such autobuild failures Signed-off-by: "Yann E.

+Subject: [PATCH] src: remove use of the __P() macro
+
+The __P() macro is a legacy compatibility macro aimed making pre-ANSI
+(i.e. K&R) compilers that do not support function prototypes happy,
+while still allowing such prototypes for ANSI-compliant compilers.
+
+Since virtually all compilers have been ANSI-compliant for a few decades
+now, use of __P() is totally useless.
+
+Furthermore, __P() is defined in the non-standard sys/cdefs.h header.
+This header is present in glibc and uClibc, and both have it included
+from many of their headers. So, sys/cdefs.h is automagically included in
+most cases and its macros are available.
+
+However, the musl C library does not provide this sys/cdefs.h header.
+Thus, the build breaks on musl.
+
+For all the above reasons, get rid of __P() wherever it is used; just
+always declare real function prototypes.
