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. | ||
