cmake: For gcc8 use linker to find paths to libc, libm, libstdc++, etc Removes the need to know/guess the paths to these libraries. Once we are gcc 8 only, we can remove -nostdlib and no additional arguments are needed for system libraries. The catch is: any time IDF overrides a symbol in the toolchain sysroot, we need an undefined linker marker to make sure this symbol is seen by linker. 2019-04-14 23:45:08 -04:00			`target_link_libraries(${COMPONENT_LIB} stdc++ gcc)`
