 Probably unrelated, but I noticed this:

configure:14244: checking if external errno exists
configure:14266: /usr/bin/gcc -o conftest -O2 -I/home/spiewe/svnws/buildroot-2013.02/output/host/usr/include  --param max-inline-insns-single=1200 -I/home/spiewe/svnws/buildroot-2013.02/output/host/usr/include -D_GNU_SOURCE -D_FILE_OFFSET_BITS=64  -DNDEBUG -L/home/spiewe/svnws/buildroot-2013.02/output/host/lib -L/home/spiewe/svnws/buildroot-2013.02/output/host/usr/lib -Wl,-rpath,/home/spiewe/svnws/buildroot-2013.02/output/host/usr/lib conftest.c  >&5
collect2: ld terminated with signal 11 [Segmentation fault]
/usr/bin/ld: configure:14269: $? = 1
configure: failed program was:
#line 14251 "configure"
#include "confdefs.h"

#undef errno
extern int errno;

int
main ()
{
errno = 2
  ;
  return 0;
}
configure:14286: result: no


 ld shouldn't segfault on something like that...



 But where it really goes wrong is here:

configure:14734: checking for termio.h
configure:14744: /usr/site/bin/cpp -I/home/spiewe/svnws/buildroot-2013.02/output/host/usr/include -D_GNU_SOURCE -D_FILE_OFFSET_BITS=64  -DNDEBUG conftest.c
configure:14741: termio.h: No such file or directory
configure:14750: $? = 1
configure: failed program was:
#line 14740 "configure"
#include "confdefs.h"
#include <termio.h>
configure:14769: result: no

 It looks like /usr/site/bin/cpp doesn't look in /usr/include. 
Why do you have a non-standard cpp anyway?
