How to disable a build for selected architectures?

[Sebastian Huber]

Hello,

the utf8proc library is not available on 16-bit targets:

m32c-rtems4.11-gcc --pipe -DHAVE_CONFIG_H   -I.. 
-I../../cpukit/../../../m32csim/lib/include   -mcpu=m32cm -O0 -g -Wall 
-Wmissing-prototypes -Wimplicit-function-declaration -Wstrict-prototypes 
-Wnested-externs -MT utf8proc/utf8proc.o -MD -MP -MF $depbase.Tpo -c -o 
utf8proc/utf8proc.o 
/home/sh/git-rtems/c/src/../../cpukit/libmisc/utf8proc/utf8proc.c &&\
mv -f $depbase.Tpo $depbase.Po

What it the best way to disable the utf8proc library build for such targets?
