The absolute file name appeared in your previous message:

We were referring to quasiquote/unquote, and yes, you did it right.

Ah, yes, that’s because CFLAGS is also used by the /native/ compiler,
hence this failure.
After a bit of research, I found ports/sysdeps/mips/preconfigure (in
libc). Apparently, it interprets the OS part of the target triplet to
determine the ABI. So, if you specify --target=mips64el-linux-gnuabi64,
it should automatically build glibc for n64.
The simplest way to do that is probably:
diff --git a/gnu/packages/cross-base.scm b/gnu/packages/cross-base.scm
index 69dc9f5..f4903d3 100644
--- a/gnu/packages/cross-base.scm

(And you can remove previous attempts to specify CFLAGS.)
Can you try that?
TIA!
