Rich Felker 28198ac3af fix passing of 64-bit syscall arguments on microblaze 
this has been wrong since the beginning of the microblaze port: the
syscall ABI for microblaze does not align 64-bit arguments on even
register boundaries. commit 788d5e24ca
exposed the problem by introducing references to a nonexistent
__syscall7. the ABI is not documented well anywhere, but I was able to
confirm against both strace source and glibc source that microblaze is
not using the alignment.

per the syscall(2) man page, posix_fadvise, ftruncate, pread, pwrite,
readahead, sync_file_range, and truncate were all affected and either
did not work at all, or only worked by chance, e.g. when the affected
argument slots were all zero.

    musl libc

musl, pronounced like the word "mussel", is an MIT-licensed
implementation of the standard C library targetting the Linux syscall
API, suitable for use in a wide range of deployment environments. musl
offers efficient static and dynamic linking support, lightweight code
and low runtime overhead, strong fail-safe guarantees under correct
usage, and correctness in the sense of standards conformance and
safety. musl is built on the principle that these goals are best
achieved through simple code that is easy to understand and maintain.

The 1.1 release series for musl features coverage for all interfaces
defined in ISO C99 and POSIX 2008 base, along with a number of
non-standardized interfaces for compatibility with Linux, BSD, and
glibc functionality.

For basic installation instructions, see the included INSTALL file.
Information on full musl-targeted compiler toolchains, system
bootstrapping, and Linux distributions built on musl can be found on
the project website:
