   4 Subject: Makefile: Remove -nostartfiles from LDFLAGS
   5
   6 Binutils linker ld does not support the flag -nostartfiles.
   7 This is interpreted as "-n -o startfiles" which fortunately has no impact
   8 on the build process. Removing -nostartfiles has no impact on the build.
   9
  10 Binutils 2.36 and later ld has improved flag parsing and throws an error if
  11 -nostartfiles is passed as an argument. Removing the flag fixes the problem.
  12
  13 Details on the Binutils ML:
  14 https://sourceware.org/pipermail/binutils/2021-June/116826.html
  15
  16 In our ld command line there are explicit
  17 -n -o $(BINDIR)/$(BOOT_NAME).elf options,
  18 hence removing -nostartfiles will not alter the build.
