kbuild: parameterize the .o part of suffix-search
The suffix-search macro hard-codes the suffix, '.o'. Make it a parameter so that the multi-search and real-search macros can be reused for foo-dtbs syntax introduced by commit 15d16d6dadf6 ("kbuild: Add generic rule to apply fdtoverlay"). Signed-off-by: Masahiro Yamada <>
