That is an exaggeration. In fact, gcc and glibc routinely change
without affecting the other.

As I understood your original proposal, it involved changing how the
dynamic linker interprets LD_LIBRARY_PATH. That change would be to
the dynamic linker, which is part of glibc. No change to gcc would be
required at all.
If such a change is adopted into glibc, then there is a part of the
program linker which also looks at LD_LIBRARY_PATH and should probably
also be changed. This is not a very important part of the linker,
though, and mainly exists to give better warnings. The linker is, of
course, part of the binutils, not part of gcc.
