[Xcb] Cannot compile 1.11.1 for arm hosts

[Alex Barker]

Hi,

I am having quite a bit of trouble compiling libxcb for arm hosts. It 
appears to try and re-link the libxcb-composite.la file against /usr/lib 
during the install phase when cross compiling.  I look thought the 
automake file and it appears to be valid and correct. Libtool should be 
calculating the rpath auto-magically for the libraries in question.  The 
strange part is this use to work, but started failing recently.  I think 
GCC 5.3 was the biggest upgrade. I am looking for any suggestions short 
of patching libtool to get this working.  I have tried rolling back 
package versions for libtool and libxcb with the same result.
