/*
 * musl — the musl C library.
 *
 * A library building block, NOT a system switch: glibc remains the
 * system libc; this package makes musl available in the store (headers,
 * static libc.a, shared libc.so + ld-musl loader, crt objects).
 *
 * CONSUMING MUSL (no musl-gcc wrapper ships in 1.2.6 — it was replaced
 * by clang-based wrappers, and we ship gcc).  Link with gcc directly:
 *
 *   gcc -nostdinc -isystem $MUSL/usr/include \
 *       -nostdlib -L$MUSL/usr/lib -Wl,-dynamic-linker,$MUSL/lib/ld-musl-x86_64.so.1 \
 *       -static -lcrt1.o -lc -lgcc ...
 *
 * or for fully static binaries, the simpler:
 *
 *   gcc -nostdinc -isystem $MUSL/usr/include -nostdlib -static \
 *       -L$MUSL/usr/lib -lcrt1.o -lc -lgcc -lgcc_eh
 *
 * where $MUSL is the store install root.  Build requires only a C
 * compiler and make; no external deps.
