I tested the 2 patch with same error.

I have no .../thirdparty/build/, but I have .../thirdparty/src/

In .../thirdparty/src/ I have only libavc1394-0.5.4.tar.xz

In .../thirdparty/ I havn't libavc1394-0.5.4, but, after patching, I
have libavc1394-0.5.4.patch1 and libavc1394-0.5.4.patch2

in thirdparty or in thirdparty/src? 

After the failed build I have also .../thirdparty/build/ with libavc1394.source
Maybe I need to apply the 0002 patch after compiling and getting the
error? I wouldn't know how to do that....

no.. for some reason both builds failed to patch configure.ac?? 

for me it exist after successfull build:

$ ls thirdparty/libavc1394-0.5.4/configure.ac -la
-rw------- 1 u0_a116 u0_a116 627 Nov 26 16:09 thirdparty/libavc1394-0.5.4/configure.ac
$

how exactly you patch? git am or simple  patch?
