[Lazarus] Build of Lazarus fails on Mac with STABS error (perhaps because of MacOSX 10.11??)

[Michael Ring]

Two or three weeks ago I switched my main computer to OSX 10.11, now I 
tried to re-compile Lazarus but compilation failed. I compile Lazarus 
quite regulary, so my guess is that this is perhaps related to OSX 10.11 
as this problem is new to me and I have not seen others talking about an 
error like this in the forum (besides a thread in may, but this seems at 
least partially unrelated as I was able to compile lazarus during the 
whole summer.

I was able to make the main compile work again by adding -gw explicitly 
to OPT:

make clean all CPU_TARGET=i386 LCL_PLATFORM=carbon OPT="-k'-framework' 
-k'ApplicationServices' -gw"

So far, so good but when I run lazbuild the build fails:


lazbuild --build-ide= --ws=carbon --cpu=i386 --compiler=/usr/local/bin/fpc

The problem seems to be that with lazbuild the Makefile defaults are 
taken, this means for some modules that they are compiled with only -g 
which means with Stabs debug info and this perhaps is not valid anymore 
on Mac.

grep "\-g" /usr/local/share/lazarus/components/debuggerintf/Makefile
....
override COMPILER_OPTIONS+=-MObjFPC -Scghi -O1 -g -gl -l -vw- -vh- 
-venibq -vm4046
....


Any ideas how to solve this?
