[HarfBuzz] Cross-compiling HarfBuzz for ios

Hi Behdad :)

So I built the two static libraries libharfbuzz.a and libicu-le-hb.a, and put the two and their respective header files into my project, replacing libicule.a and its header files like so:

    /Users/anitahui/Projects/main/Gladiator/uswish/samples/FocusAE/src/../../../thirdparty/prebuilt/ios/arch-arm/Debug/libicui18n.a         
    /Users/anitahui/Projects/main/Gladiator/uswish/samples/FocusAE/src/../../../thirdparty/prebuilt/ios/arch-arm/Debug/libiculx.a 
    /Users/anitahui/Projects/main/Gladiator/uswish/samples/FocusAE/src/../../../thirdparty/prebuilt/ios/arch-arm/Debug/libharfbuzz.a 
    /Users/anitahui/Projects/main/Gladiator/uswish/samples/FocusAE/src/../../../thirdparty/prebuilt/ios/arch-arm/Debug/libicu-le-hb.a 
    /Users/anitahui/Projects/main/Gladiator/uswish/samples/FocusAE/src/../../../thirdparty/prebuilt/ios/arch-arm/Debug/libicuuc.a 
    /Users/anitahui/Projects/main/Gladiator/uswish/samples/FocusAE/src/../../../thirdparty/prebuilt/ios/arch-arm/Debug/libicudata.a 

And I'm getting the error below for amv7 as well as armv7s:

Do you have any ideas as to what I'm doing wrong or any thing I may have missed? 

Thanks!

D'oh.  Up to you whether you do static or dynamic linking, but icu-le-hb uses
HarfBuzz, so yes, you need libharfbuzz one way or another.  If you want
all-static, they you need libharfbuzz.a.

Does this mean that I need to have ICU in order to build libharfbuzz-icu.a? Please correct me if I'm wrong but I'm guessing that I need libharfbuzz-icu.a with libicu-le-hb.a in order to replace libicule.a.
