so there is endian issue with dynamic linking

musl c code should not depend on endianness
(eg on x86 it works fine) so i guess the issue
is mips specific

maybe something in mips asm

or maybe there is some difference between
mips and mipsel other than the endianness?
(elf header or auxv something, or the build
toolchain is different in some way)

can you run libc.so itself?

/lib/libc.so

should print a usage message

if it works then try to run it as ldd on
a dynlinked binary
