$ gcc -shared -fPIC -flto=4 -o x.so isl.o -v
...
make -f /tmp/ccj2DsQs.mk -j4 all

/usr/local/bin/ld:
/usr/lib/gcc/x86_64-redhat-linux/8/../../../../lib64/../lib64/crt1.o: in
function `_start':
(.text+0x24): undefined reference to `main'
collect2: error: ld returned 1 exit status
make: *** [<builtin>: all] Error 1
lto-wrapper: fatal error: make returned 2 exit status
Since all.c matches the target "all", make tries to create "all".
