And many others.
When mp4v2 is configured with --disable-debug (which the infrastructure will
pass unless BR2_ENABLE_DEBUG is enabled) then the configure script tries to
filter out any -g* debugging flags with the following logic:
if test "$enable_debug" = "no"; then
changequote(<<,>>)dnl
if test "$GCC" = "yes"; then
CFLAGS=`echo "$CFLAGS" | sed -e 's/-g[^ ]*[ ]*//' -e 's/^ //' -e 's/ $//'`
fi
if test "$GXX" = "yes"; then
CXXFLAGS=`echo "$CXXFLAGS" | sed -e 's/-g[^ ]*[ ]*//' -e 's/^ //' -e 's/ $//'`
fi
changequote([,])dnl
fi
This logic is unfortunately buggy as it also strips up arguments like
-mfloat-gprs=double breaking the build when the powerpc SPE variants are
-used.
Instead of fixing the sed invocation we can simply pass --enable-debug to
configure as the debugging flag is not used for anything else.
