config.mak.dev: fix typo when enabling -Wpedantic

In ebd2e4a13a (Makefile: restrict -Wpedantic and -Wno-pedantic-ms-format better, 2021-09-28), we tightened our Makefile's behavior to only enable -Wpedantic when compiling with either gcc5/clang4 or greater as older compiler versions did not have support for -Wpedantic. Commit ebd2e4a13a was looking for either "gcc5" or "clang4" to appear in the COMPILER_FEATURES variable, combining the two "$(filter ...)" searches with an "$(or ...)". But ebd2e4a13a has a typo where instead of writing: ifneq ($(or ($filter ...),$(filter ...)),) we wrote: ifneq (($or ($filter ...),$(filter ...)),) Causing our Makefile (when invoked with DEVELOPER=1, and a sufficiently recent compiler version) to barf: $ make DEVELOPER=1 config.mak.dev:13: extraneous text after 'ifneq' directive [...] Correctly combine the results of the two "$(filter ...)" operations by using "$(or ...)", not "$or".
