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.

/* These ROM functions call respective entries in the syscall table.
|
|
They are called by other ROM functions (mostly from newlib).
|
|
We don't link to them directly, since in IDF there are actual
|
|
implementations of these functions, with same names.
|
|
|
|
I.e.:
|
|
|
|
times (in ROM) -> _times_r (in ROM) -> syscall table entry _times_r -> _times_r (in IDF)
|
|
|
|
Hence the following entries are provided only for reference
|
|
and commented out.
