Subject: perl: fix build caused by bison generated code
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=8a4c8deee9af6fa1a1e906c52d7d49a32434464c;p=buildroot.git

perl: fix build caused by bison generated code

This commit makes sure the date of a C file is newer than the date of
the corresponding Bison source file, so that the build process doesn't
try to regenerate it. This avoids the need to have host-bison as a
dependency for the perl build.

Fixes:
