I’ve just gone through this process, pretty much exactly
as Sergey described, including digging around trying to
find info on what patches, versions, etc. of the tools
are required, and agree that it’s a sort of black magic.
Saying “use an official released version to build your
system” becomes a lot more palatable if there would always
be an up-to-date trio of officially released binutils/glibc/gcc
that all work together.  Easier said than done, I agree, but
that would be a wonderful thing to achieve.   When these 3
pieces achieve alignment so rarely, it doesn’t suprise me that
vendors dig in and make their own modifications.

Another user’s perspective,

Ken

p.s. and thanks to all the folks working on these tools, it’s
definitely appreciated.
