Subject: [PATCH] tccelf: Fix static linking with musl
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

tccelf.c:
- tcc_add_runtime()
    Add a second tcc_add_library(s1, "c"). The libtcc1.a references at
    least abort() from the C library. After libtcc1.a the libc.a needs
    to be linked again to resolve abort(). For similar reasons gcc
    passes --start-group -lgcc -lc --end-group to the linker.

    This solves:

    ./configure '--sysincludepaths=<musl>/include:{B}/include' \
                '--libpaths={B}:<musl>/lib' \
                '--crtprefix=<musl>/lib' \
                '--tcc-switches=-static'
    make -j
    make test
    …
    ------------ hello-exe ------------
    tcc: error: unresolved reference to 'abort'
