 Another nail in the coffin for the use of gcc42 to build git,
 unfortunately.

 It appears that with the most recent update to curl, git now no longer
 builds using gcc42 (stock system gcc42, 10.5 PPC)

 rolling back to `curl @7.55.0_0+ssl` allows a successful build of git
 using `gcc-4.2`.

 gcc6 builds `git at 2.4.1` against `curl @7.55.1_0+ssl` without issue
 however.

 It looks like we'll have to consider blacklisting gcc42 for building the
 current git against the current curl; this could cause some bootstrap
 issues as gcc6 has a number of build dependencies to consider, and some of
 them may use git... have to check.
