sh: rename suffix-y to suffix_y
'export suffix-y' does not work reliably because hyphens are disallowed
in shell variables.
A similar issue was fixed by commit 2bfbe7881ee0 ("kbuild: Do not use
hyphen in exported variable name").
If I do similar in dash, ARCH=sh fails to build.
$ mv linux linux~
$ cd linux~
$ dash
$ make O=foo/bar ARCH=sh CROSS_COMPILE=sh4-linux-gnu- defconfig all
make[1]: Entering directory '/home/masahiro/linux~/foo/bar'

The maintainer of GNU Make stated that there is no consistent way to
export variables that do not meet the shell's naming criteria.
(https://savannah.gnu.org/bugs/?55719)
Consequently, you cannot use hyphens in exported variables.
