menuconfig: wrap long help lines
Help text for certain config options is very extensive (the text includes the names of all other options the option in question depends on). Long lines are not wrapped, making it impossible to see the list without scrolling horizontally. This patch adds some logic which wraps help screen lines at word boundaries to prevent truncating. Tested by running ARCH=powerpc make menuconfig O=/tmp/build which shows that the long lines are now wrapped, and ARCH=powerpc make xconfig O=/tmp/build to demonstrate that it still compiles and operates as expected.
