Hi Marcus,
thanks for the patch. Applied and pushed.
best regards Waldemar

The _dl_auxvt is also used on non shared builds to access the values of the vector from getauxval. Putting the definitions in ldso.h leads to issues because that header also implements fcntl.h functionality making it incompatible with files that include that header directly.
Factor out the _dl_auxvt related declarations to a new header dl-auxvt.h and include from ldso.h as well as include it directly from __uClibc_main.c to make the definitions available.
