* Upgrade to upstream newlib 4.0.0 release Includes 64 bit time_t and 5 years of updates. Binary incompatible with libraries which use time_t (due to the size difference). Recompiling with the new newlib should be sufficient for most libraries, assuming source is available. * Remove tools/sdk/libc directory, it isn't used anywhere Somewhere along the line the copy of libc in tools/sdl/libc was taken out of the build process. Files in there are not used, take add'l time to build and install on a toolchain release, and just cause confusion. Remove them. * Fix 64-bit time for LittleFS The core was setting 64-bit times automatically on new file creation or updates, but would fail when attempting to read them back due to 64/32b confusion. Now attempt to read 64b time, and if that fails fallback to reading 32b time to allow both old and new FS to preserve timestamps. * Update to jjsuwa-sys3175 additions to GCC and newlib @jjsuwa-sys3175 contributed multiple patches to GCC, included in the toolchain, as well as a slightly faster pgm_read_byte() macro. * Rebuild w/addl GCC patches, new BearSSL flags * Remove copied libgcc.a file, is contained in toolchain
