 I don't know if it is clang or ld or a combination of both, I am no longer
 able to build ArcticFox on 10.6 32bit. Failure is the following:


 {{{
  0:21.11 DEBUG: configure:2313: checking whether the C compiler
 (/opt/local/bin/clang-mp-6.0 -march=pentium-m -mtune=pentium-m -std=gnu99

  0
 }}}

 this used to work and the same option is used on 10.6 64bit or on 10.7
 64bit and there it works. I don't know what changed on 32bit.

 My clang is:


 {{{
   clang-6.0 @6.0.1_6+defaultlibcxx+emulated_tls (active)
 }}}

 while on the linker side it is this:


 {{{
   ld64 @3_6+ld64_127 (active)
   ld64-127 @127.2_14+llvm34 (active)
 }}}

 I wonder if these are correct and invocated.

 $ ld-127 -no_data_in_code_info
 ld: unknown option: -no_data_in_code_info

 tells me probably it is too old. On

Comment:

 I checked on 10.6.8 64bit and I have ld64-450.3 which supports the said
 option.

 Are newer linkers not available for 32bit? or do they have issues?

 The option gets added automatically during the build configuration, I do
 not explicitly add it.

 {{{

 # Ensure the updated linker doesn't generate things our older build tools
 # don't understand.
 ldflags="$ldflags -Wl,-no_data_in_code_info"
 export LDFLAGS="$ldflags"
 }}}


 this is an option added in Firefox.... so it is not directly MacPorts
 issue, but the issue essentially that 32bit lags behind 64bit.
