This happens when a configure.ac script has a AC_RUN_IFELSE() test. It
tries to run programs, which is not possible when cross-compiling. So
you need to tell the configure script what is the result of those
tests, so that it doesn't execute them. In the case of Git, it should
be:

GIT_CONF_ENV = \
	ac_cv_fread_reads_directories=<yes or no> \
	ac_cv_snprintf_returns_bogus=<yes or no>

Of course, you still have to figure out what's the right value to put.

Then just use GIT_VERSION = 1.8.2.1

Just curious, why are you packaging Git? Remember that we are
deprecating the support for the toolchain on the target, so if what you
want to achieve is build C/C++ code on the target, you're probably not
on the right track.

Best regards,
