Kim Phillips c0cd6f4de9 perf llvm-utils: Remove bashism from kernel include fetch script
[ Upstream commit f6432b9f65001651412dbc3589d251534822d4ab ]

Like system(), popen() calls /bin/sh, which may/may not be bash.

Script when run on dash and encounters the line, yields:

 exit: Illegal number: -1

checkbashisms report on script content:

 possible bashism (exit|return with negative status code):
 exit -1

Remove the bashism and use the more portable non-zero failure
status code 1.
