+Subject: [PATCH] Add RISC-V endian detection
+
+3rdparty/msgpack-c/include/msgpack/predef/other/endian.h (which comes
+from Boost) two ways of detecting the endianess:
+
+ (1) It includes <endian.h> if BOOST_LIB_C_GNU is defined, and then
+     use __BYTE_ORDER to decide the endianness.
+
+ (2) Otherwise, if (1) was not possible for some reason, it uses
+     architecture defines to decide the endianness.
+
+(1) works perfectly fine with glibc toolchains, because
+BOOST_LIB_C_GNU is defined, but it doesn't work with musl. Due to
+this, <endian.h> is not included, __BYTE_ORDER is not defined, and
+method (1) does not work, causing build failures on musl toolchains
+that don't have explicit handling by architecture name (method 2).
+
+So this commit fixes RISC-V musl build by adding support for the
+__riscv architecture define, to determine that the endianness is
+little endian.
