The flag nostartfiles is not a flag of ld. So it shouldn't appear in LDFLAGS += -nostartfiles
I assume that we should change
`LDFLAGS += -nostartfiles -nodefaultlibs`
to
`CXXFLAGS += -nostartfiles -nodefaultlibs
`
in every board Make.defs
It works for my board

Oh this issue is now on Debian based distros as well?
We've seen this (a general did you mean --option instead of -option) in arch based distros. We couldn't see any references in the GNU project where -option is replaced with --option, so we assumed an issue in the Arch package.
Anyway, did you try to download the toolchain as described in https://github.com/apache/incubator-nuttx/issues/3209?

The answer https://sourceware.org/pipermail/binutils/2021-June/116826.html
from nickc@redhat.com is

This is caused by Binutils being updated to the 2.36.x line.
This is fixed by PR #3836
This is now documented at Release Notes for the (future) NuttX-10.2 release:
[https://cwiki.apache.org/confluence/display/NUTTX/NuttX+10.2#ld-now-called-through-gcc](https://cwiki.apache.org/confluence/display/NUTTX/NuttX+10.2#ld-now-called-through-gcc)
