How can I port embedding Mozilla into a STB (CPU: 486-133)?

[李偉新 James Lee]

Hi,
  I am a Chinese Engineer. My boss request me port embedded Mozilla into
a STB. The provider of CPU is STPC, and the type is Consummer II. It is
said Consummer II is compatible with Intel 486-133. However, you know
Mozilla requirement is PII 233 at least.
  I found TestGtkEmbed depended on linux library(\lib\i686\libc++...).
But my CPU is 486.  So, TestGtkEmbed can not be launched on this
platform.
  How can I solve this problem?

  Thanks everybody.
