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