geninfo incompatible with LLVM gcov 7.0

[sakra]

The code in geninfo to determine the version of the gcov tool no longer works for LLVM gcov 7.0. It results in the following error:

geninfo: Use of uninitialized value $version_string in substitution (s///) at /usr/local/bin/geninfo line 1914.
geninfo: Use of uninitialized value $version_string in pattern match (m//) at /usr/local/bin/geninfo line 1917.
geninfo: Use of uninitialized value $version_string in pattern match (m//) at /usr/local/bin/geninfo line 1930.
geninfo: Use of uninitialized value $gcov_version_string in pattern match (m//) at /usr/local/bin/geninfo line 3720.
geninfo: Use of uninitialized value $gcov_version_string in pattern match (m//) at /usr/local/bin/geninfo line 3720.

The output of gcov --version under OS X:

 $ gcov --version
 Apple LLVM 7.0.0 (clang-700.0.72)

Thanks for reporting. This issue should be fixed with commit 1ad4f77.
