Comment (by kencu):

 I did build it with gcc7 due to [ticket:60740]

 perl5.28 will build with gcc-4.2 but only if it can link against
 libssp_nonshared from a newer libgcc that happens to be installed, so that
 seemed too tenuous so I just built it with gcc7, that had an official call
 in to libgcc7 to supply the libssp_nonshared.

 but it appears that has more repercussions, so maybe the better fix is to
 stop perl building against libssp_nonshared when building with gcc-4.2...
