There is CT_LIBC_GLIBC_CONFIGPARMS that can be set in the menuconfig.
The value set in this variable is used to create a file named 'configparms'
in the top-level of the build dir. That file is then included from the
Makeconfig makefile.

It is possible to use it to pass one value. Passing more is not yet possible.
I can work something to handle more. Care to try the attached patch?

Regards,
Yann E. MORIN.
