[microblaze-uclinux] Build errors with uclinux-dist: missing _syscall3

[Dana Goyette <DGoyette@xxxxxxxxxxx>]

Now that I've gotten the kernel booting (new device-tree generator made
it work -- thanks!), it's time for me to get userspace up.  I'm
attempting to build uclinux-dist for the same XUPV5-LX110T board, but I
am running into build errors.

If I just try to "make", the obsolete mb-gcc fails with "your compiler
miscompiles the __weak directive".

If I edit ./vendors/config/microblaze/config.arch to instead use the
newer mb-linux-gcc, the build fails in a different place, which I assume
is caused by a missing definition of _syscall3 on Microblaze :

mb-linux-gcc  -Wall -Wstrict-prototypes -Wno-trigraphs
-fno-strict-aliasing  -Os -funit-at-a-time  -O2 -g -fomit-frame-pointer
-pipe -fno-common -fno-builtin -Wall -msoft-float -mxl-pattern-compare
-mxl-soft-mul -mxl-barrel-shift -mno-xl-soft-div -DEMBED
-fno-stack-protector -fno-builtin -nostdinc -D_LIBC -I../../../include
-I. -isystem

(Side note: If I set uClinux-dist to use glibc instead of uClibc, it
errors out on lack of a Makefile in the glibc directory.)

Also, I tried about 8 times to reply to my previous thread about booting
the kernel, but each time, Thunderbird told me that the newsgroup was
"unidirectional", and the post didn't show up.  Even if I explicitly
wrote to the reply-to address (
microblaze-uclinux-rVRm/Wmeqae7NGdpmJTKYQ@xxxxxxxxxxxxxxxx ), my posts
still did not appear.  I finally had to post to 
microblaze-uclinux@xxxxxxxxxxxxxx  (which is not in any of the headers 
of any of the messages), to get the message to appear.

Thanks again for the help.
