+Subject: [PATCH] Disable tests
+
+Tests are causing build failures on some architectures that are missing
+a proper fenv.h, so just disable them.

+Subject: [PATCH] pixman-private: include <float.h> only in C code
+
+<float.h> is included unconditionally by pixman-private.h, which in
+turn gets included by assembler files. Unfortunately, with certain C
+libraries (like the musl C library), <float.h> cannot be included in
+assembler files:
+
+  CCLD     libpixman-arm-simd.la
+/home/test/buildroot/output/host/usr/arm-buildroot-linux-musleabihf/sysroot/usr/include/float.h: Assembler messages:
+/home/test/buildroot/output/host/usr/arm-buildroot-linux-musleabihf/sysroot/usr/include/float.h:8: Error: bad instruction `int __flt_rounds(void)'
+/home/test/buildroot/output/host/usr/arm-buildroot-linux-musleabihf/sysroot/usr/include/float.h: Assembler messages:
+/home/test/buildroot/output/host/usr/arm-buildroot-linux-musleabihf/sysroot/usr/include/float.h:8: Error: bad instruction `int __flt_rounds(void)'
+
+It turns out however that <float.h> is not needed by assembly files,
+so we move its inclusion within the #ifndef __ASSEMBLER__ condition,
+which solves the problem.
