I have started a build of gnulib on that host, and it will run daily
from now on.

But testing strstr (using current gnulib) manually passes:

...
checking for getpagesize... yes
checking for mmap... yes
checking for MAP_ANONYMOUS... yes
checking for memchr... yes
checking whether memchr works... no
checking bp-sym.h usability... no
checking bp-sym.h presence... no
checking for bp-sym.h... no
checking whether strstr works in linear time... no
...
PASS: test-strstr

I checked, and the gnulib strstr replacement is used.
