sys-libs/compiler-rt: Override start symbol when adding -nostartfiles to LDFLAGS Trying to link executables for the configure checks generates linker warnings (in the CMake logs) like: "warning: cannot find entry symbol _start; defaulting to 0000000000001000". Moreover, with flags like -flto or -Wl,--gc-sections, the linker can discard all code, rendering the checks useless. Set main as entry symbol when linking with -nostartfiles to avoid both issues. (Note that the binaries would still crash, but that doesn't matter since they are never executed.)
