Entirely possible, as there was in fact an intervening GCC upgrade, with
the following ChangeLog stanza:

Comparing the "Build environment" sections of [1] (good) and [2] (bad)
also indicates some other upgrades, though GCC is my prime suspect if
this is in fact a toolchain regression.
- binutils 2.29.1-2 -> 2.29.1-3, featuring a fix for PR ld/22626.
- glibc 2.25-5 -> 2.26-3.
- linux-libc-dev (kernel headers) 4.14.2-1 -> 4.14.12-2.
- Upgrades to various libraries and utilities outside the central
  toolchain.

Thanks for the analysis, and sorry for the noise if this turns out to be
a toolchain bug.
