Thanks for your hints.
As far as i understand the cross compile system - the uclibc built by crossdev
is the one the compiled software for the target to be linked against.
Resulting from this the uclibc must reflect the target system (here
especially: no-mmu).
Hope i am right here.
So i tried to do this using the savedconfig use-flag. I broke to compilation
process while it is compiling uclibc. Then i did a "make menuconfig" (in
/var/tmp/...) and disabled MMU and (as followup) the target file format to
"STATIC FLAT" (i assume PIE is also not possible because of the missing MMU).
At restarting the crossdev execution i got an error while installing uclibc.
The compile step of the ebuild went well. At the installation stage it
complains that it is missing "utils/ldconfig.host" when doing newbin. This can
be seen in the ebuild in the src_install step. The offending line is
newbin utils/ldconfig.host ${CTARGET}-ldconfig | die
So this file seems not to be generated during the uclibc built process when
PIE is off. This applies to ldd.host also.
What to do now?
Skip this files in the ebuild ?
Or am i doing too much and the uclibc code is clever enough to disable mmu
logic when the taget it is running on doesn't have it ?
