build system: avoid build failure during bisection
Commit 4bdc914ff (build system: fix compiler warnings) added a
test on the return value of fgets() in split-include.c.
During bisection it's possible to go back to a state where a
configuration value didn't exist. This results in an empty
include file corresponding to the missing feature. If a
subsequent bisection returns to a state where the feature exists
split-include treats the empty file as an error and the build
fails.
Add a call to ferror() to distinguish between fgets() failing
due to an error and due to there being no data to read.
