Commit Message

Commit cafa0010cd51 ("Raise the minimum required gcc version to 4.6")
bumped the minimum GCC version to 4.6 for all architectures.

This effectively reverts commit da541b20021c ("objtool: Skip
unreachable warnings for GCC 4.4 and older"), which was a workaround
for GCC 4.4 or older.
