vmlinux.lds.h: Fix incomplete .text.exit discards
Enabling CONFIG_GCOV_PROFILE_ALL=y causes linker errors on ARM: `.text.exit' referenced in section `.ARM.exidx.text.exit': defined in discarded section `.text.exit' `.text.exit' referenced in section `.fini_array.00100': defined in discarded section `.text.exit' And related errors on NDS32: `.text.exit' referenced in section `.dtors.65435': defined in discarded section `.text.exit' The gcov compiler flags cause certain compiler versions to generate additional destructor-related sections that are not yet handled by the linker script, resulting in references between discarded and non-discarded sections. Since destructors are not used in the Linux kernel, fix this by discarding these additional sections. Reported-by:Arnd Bergmann <arnd@arndb.de> Tested-by:
