Revert "meson.build: default to -gsplit-dwarf for debug info"

Browse Source 
This reverts commit 563b1a35ed1f1151505d4fe5f723827d1b3fd4bc.

Split debug info support is broken when cross compiling
(https://gcc.gnu.org/bugzilla/show_bug.cgi?id=99973).  People
that would like to use it can add it via --extra-cflags.
