Still blowing up -- RPI2 crossbuild

[Karl Denninger]

From an AMD64 machine using the "mk" script, now that hardware
floating-point has turned into the default it appears that at the same
time an include file has gone missing.

I get:

--- flt_rounds.So ---

'softfloat-for-gcc.h' file not found
#include "softfloat-for-gcc.h"
         ^
1 error generated.
*** [flt_rounds.So] Error code 1

The code in question in flt_rounds.c is:

#include <fenv.h>
#include <float.h>

#ifndef __ARM_PCS_VFP
#include "softfloat-for-gcc.h"
#include "milieu.h"
#include "softfloat.h"
#endif

And indeed in src/lib/libc/arm/softfloat that file is not there (the
other two are)

Adding "#define    __ARM_PCS_VFP" (so the test for those three includes
always fails) appears to work. 

But then the crossbuild blows up here:

--- kerberos5/lib/libhdb__L ---
hdb-sqlite.So: In function `hdb_sqlite_make_database':
/pics/CrossBuild/src/kerberos5/lib/libhdb/../../../crypto/heimdal/lib/hdb/hdb-sqlite.c:(.text+0x480):
undefined reference to `__aeabi_dcmpeq'
cc: error: linker command failed with exit code 1 (use -v to see invocation)
*** [libhdb.so.11] Error code 1

bmake[4]: stopped in /pics/CrossBuild/src/kerberos5/lib/libhdb
1 error

bmake[4]: stopped in /pics/CrossBuild/src/kerberos5/lib/libhdb
*** [kerberos5/lib/libhdb__L] Error code 2

Will see what I can find later on this...
