this overhauls part of the build system in order to support multiple toolchain wrapper scripts, as opposed to solely the musl-gcc wrapper as before. it thereby replaces --enable-gcc-wrapper with --enable-wrapper=..., which has the options 'auto' (the default, detect whether to use wrappers), 'all' (build and install all wrappers), 'no' (don't build any) and finally the options named after the individual compiler scripts (currently only 'gcc' is available) to build and install only that wrapper. the old --enable-gcc-wrapper is removed from --help, but still available. it also modifies the wrappers to use the C compiler specified to the build system as 'inner' compiler, when applicable. as wrapper detection works by probing this compiler, it may not work with any other.
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
