Ok, I finally found it.

Also "BSD obsolete signal functions" (UCLIBC_HAS_OBSOLETE_BSD_SIGNAL) under
"Advanced Library Settings" must be enabled to make this work.

And looking into lipthread/nptl/sem_open.c I revealed that __fxstat64() is
basically equivalent to fstat64() if Largefile support is enabled in uClibc
and otherwise just fstat().

So I can hack that into my application or maybe directly into sys/stat.h

Case solved :)
