musl

Depends on mawk
install-tools is for the wrapper musl-gcc
Do not set the prefix to /usr, /usr/local, or / unless upgrading libc on an existing musl-based system (this will break your existing system after running make install making it difficult to recover)
The dynamic linker searches for shared libraries at run time under directories listed in /etc/ld-musl-$ARCH.path separated by colons or newlines
If the dynamic linker has been installed in a non-default location, the path needs to reside at that location (../etc relative to the chosen syslibdir)
DT_RELR support (-z pack-relative-relocs) has been upstreamed, and reduces size by 5 - 8%
Does musl conflict/replace libssp (the standalone package)
gencat requires queue.h
Alpaquita statically links against glibc-string; a library that provides extra performance optimizations for string manipulation and memory functions
Alpaquita has patches to fix ldd output for static-pie executables
Chimera surgically removes musl’s malloc-ng and replaces it with mimalloc
LC_ALL overrides category-specific variables, and LANG provides a default for any category not set
MUSL_LOCPATH - Colon-separated list of paths that will be searched for locale definitions. The requested locale name string will used as a filename and searched in each path component. If unset, locale files are not loaded and only the “C” locale is available. This variable is completely ignored in programs invoked setuid, setgid, or with other elevated capabilities
musl provides empty crti.o and crtn.o for legacy .init and .fini support; use .init_array and .fini_array instead as they are the modern implementation (this means that gcc and binutils should be configured with --enable-initfini-array)
Log messages will be discarded if /dev/log is absent
