Linker Flag Investigation: -nolibc vs -nostdlib/-nodefaultlibs #125

Open phillipjohnston opened 4 years ago

Shoudl our libc use this flag? instead of nostdlib or nodefaultlibs?

-nolibc
Do not use the C library or system libraries tightly coupled with it when linking. Still link with the startup files, libgcc or toolchain provided language support libraries such as libgnat, libgfortran or libstdc++ unless options preventing their inclusion are used as well. This typically removes -lc from the link command line, as well as system libraries that normally go with it and become meaningless when absence of a C library is assumed, for example -lpthread or -lm in some configurations. This is intended for bare-board targets when there is indeed no C library available.

This might eliminate the need to handle #124
