[Debian-med-packaging] Bug#896843: FTBFS: incorrect CPPFLAG for powerpc*

[Barry Arndt]

Source: ctsim
Version: 6.0.2
Severity: serious
Tags: l10n patch
Justification: fails to build from source (but built successfully in the past)

Dear Maintainer,

FTBFS of ctsim-6.0.2 on ppc64el reported from unicamp.

The build log reported:
g++: error: unrecognized command line option '-faltivec'; did you mean '-maltivec'

The correct flag for ppc64el (as well as powerpc*) is -maltivec.

I changed -faltivec in configure.ac to -maltivec as follows:

--- ctsim-6.0.2.orig/configure.ac
+++ ctsim-6.0.2/configure.ac
@@ -137,7 +137,7 @@ case $target_cpu in
         CXXFLAGS="$CXXFLAGS $CPUEXT_FLAGS $SIMD_FLAGS"
         ;;
     powerpc*)
-        ARCH_OPTION="-fno-common -faltivec";;
+        ARCH_OPTION="-fno-common -maltivec";;
     armv1*|armv2*|armv3*|armv4*|armv5*|armv6*)
         ARCH_OPTION="-ffast-math";;
     armv7*|armv8*)

I then ran autoconf.  After that, the package build properly.

This fix should also fix the FTBFS of ctsim on 
powerpc, powerpcspe, and ppc64.
