Re: toolchain/57146 (COPY_SYMTAB is broken by MKCTF=yes)

[Luke Mewburn <luke%mewburn.net@localhost>]

I've done some further analysis inspired by Martin's comment
that the published releases are too large, and I think that
they're built with MKDEBUG=yes.

tl;dr: The combination of both MKCTF=yes and MKDEBUG=yes
causes the size blowout. Just one or the other of these
options enabled does not seem to be that much of an issue.

Seeking input from ARM toolchain gurus for further advice.


Testing GENERIC compiles with various combinations of MKCTF and MKDEBUG.
In these results:
- c0 == MKCTF=no
- c1 == MKCTF=yes
- d0 == MKDEBUG=no
- d1 == MKDEBUG=yes
