gcc/config.gcc
Or you could port gold to AVR and use the plugin :-)
I hadn't checked, but yeah, since AVR is an ELF platform, that's a nice
solution too. There might still be reason to build a collect2, for interop
with older binutils.

Thank you David and Rafel
I will dig further into collect2. I had noted that avr.h has the following:
/* This is undefined macro for collect2 disabling */
#define LINKER_NAME "ld"
Also, the MINGW host is the most significant for the AVR target - and
problems with collect2 may be related to maintaining compatibility to that.
