Improves compatibility with other toolchains, and allows a single TCC
build/install to support multiple targets, eg. glibc and musl. Currently the
convention is to build/install TCC twice (see eg. tcc-musl on the AUR). A
hack[1] allows an existing TCC to partially support glibc and musl, with
caveats. For most compilers, to target musl I would run:
cc -nostdinc -nostdlib -Wl,-nostdlib \
-isystem /usr/lib/musl/include -L /usr/lib/musl/lib \
-Wl,-I/lib/ld-musl-`uname -m`.so.1 \
-l:crt1.o -l:crti.o [FILES...] -lc -l:crtn.o
These patches allow the above command line to work on TCC (obviously with -ltcc1
appended).
