main/libsndfile: fix varargs bug on mips{el}

This upstream patch fixes multi.rf64 test failure on mipsel{n8hf} at least.

Note the bug was reported for armv7hl so arm* check() should probably be re-enabled.

+    src/rf64.c: Fix varargs related bug
+    
+    C's <stargs.h> functionality isn't type checked so that passing an
+    `sf_count_t` (64 bits) by mistake in place of a `unit32_t` can cause
+    errors. This would be fine if it was an error on every architecture
+    and platform, but its not. This particular problem only manifested
+    on armhf and some other Arm architectures. It was not an issue on
+    32 bit x86.
+    
+    I have now fixed variants of this same bug several times.
+    
+    Closes: https://github.com/erikd/libsndfile/issues/229
