printf() broken due to missing u8_strlen

[pao]

I see that gnulib provides it, but there's no references to "unistr.h" anywhere in the source.

julia> strlen("abcdא")
dlsym: julia: undefined symbol: u8_strlen

julia> strlen("abcdא")
dlsym: julia: undefined symbol: u8_strlen

julia> strlen("abcdא")
Segmentation fault

Works fine for me. May need a cleanall since this is a symbol that didn't used to be exported from src/support. Also, may only break on Linux because I think the default symbol visibility on OS X is everything. I always forget to put things in the export map because it has no effect on me. The thing to do might be to figure out how to get OS X to actually not export symbols that aren't explicitly exported.

Yep, that was it. Needed a cleanall.

Are you compiling with GCC or Clang? It looks like -fvisibility=hidden should work with either GCC or Clang. I admittedly have no idea how symbol exports are set up for Julia.

[StefanKarpinski]

Still compiling with gcc until Apple switches to clang.

Fixed properly in 8dc8b94

I cherry-picked this from my windows branch. It's quite annoying otherwise. Rebuilding is now automatic
