Patch from Ralf Corsepius <corsepiu@…>:

The patch below actuallly consists of two patches:
1) moving librpc to c/src/librpc similar to what has been done to librtems++
2) reworked configure scripts, many safety and dependency checks added to
aclocal/*.m4 macros + configuration fixes.

To apply:

mkdir c/src/librpc
mkdir c/src/librpc/src
cp c/src/lib/librpc/*.c c/src/librpc/src
cp c/src/lib/librpc/Makefile.in c/src/librpc/src
mkdir c/src/librpc/include
mkdir c/src/librpc/include/rpc
cp c/src/lib/include/rpc/* c/src/librpc/include/rpc
patch -p1 < ../rtems-rc-19990820-7.diff
rm -rf c/src/lib/librpc
rm -rf c/src/lib/include/rpc
./autogen

The additional checks in aclocal/*m4 macros add rather restrictive, sometimes
unnecessarily restrictive constraints on the sequence of how macros can be
used in a configure.in script. Adding them has let my problems with some more
complicated configuration options vanish. Apparently some macros had not been
in the required order .


Now I still get some linking errors for some cpus and bsps, esp when linking
cdtest, but also at other locations:

e.g. this happens for mips64orion/p4600:
