The recent addition of a RISC-V musl toolchain uncovered an issue in
Boost's endianness detection. Boost endianness detection only works
for C libraries that pretend to be glibc *or* if the architecture is
explicitly handled by Boost endian.h header. Neither were true for
RISC-V musl, so we slightly patch boost to fix this problem.
