llvm dev - Oct 2011 - [LLVMdev] The make install fails in cross-compile mode

Hi,

I cross-compile llvm/clang. The build platform is x86_64-linux-gnu. The host
platform is mips-linux-gnu. Llvm and clang built successfully but "make
install" shows the following error:

% make install
llvm[0]: Installing Release+Asserts
/home/simon/work/install/clang/bin/llvm-tblgen
strip: Unable to recognise the format of the input file
`/home/simon/work/install/clang/bin/llvm-tblgen'
/usr/bin/install: strip process terminated abnormally
make: *** [/home/simon/work/install/clang/bin/llvm-tblgen] Error 1

The problem is that "install" is run with "-s" argument to
strip symbols but always uses default "strip" executable even in
cross-compile mode. To fix the bug I check for the "strip" executable
in the configure.ac and provide the result to the "install" command
using "--strip-program" argument. The patches are attached to this
email.

  Nice work. Before this, I just ignore the failure and leave them unstriped.
Maybe this should go llvm-commits?

You guys are aware that this feature is specific to GNU install, right? BSD
install--and incidentally, Mac OS X uses BSD install--does not have this.
Congratulations: you just broke installing on Mac OS and the BSDs. I'm going
to revert this change right away.
