commit 2f853dd6b9a95d5b13ee8f9df762125e0588df5d moved the error handling for $(ARCH) not being set such that it applied to all targets, including clean and distclean. previously these targets worked even in an unconfigured tree. to restore the old behavior, make most of the makefile body conditional on $(ARCH) being set/non-empty and produce the error via a fake "all" target in the conditional branch for the case where $(ARCH) is empty.
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
