PDCurses: pdcscrn.c: Use `#ifdef` instead of `#if CONFIG_SPEAKER`
Building libpayload with the PDCurses backend the following warning is shown. /src/coreboot/payloads/libpayload(master) $ make clean /src/coreboot/payloads/libpayload(master) $ make […] CC curses/pdcurses-backend/pdcscrn.libcurses.o curses/pdcurses-backend/pdcscrn.c: In function 'PDC_scr_open': curses/pdcurses-backend/pdcscrn.c:75:5: warning: "CONFIG_SPEAKER" is not defined [-Wundef] […] The GCC documentation states [1] In some contexts this shortcut is undesirable. The -Wundef option causes GCC to warn whenever it encounters an identifier which is not a macro in an ‘#if’. and therefore use `#ifdef` [2] to silence this warning. No functional change is done, as `CONFIG_SPEAKER` is assigned the value `Y` when defined. There was some discussion going on the list [3], but my points in there turned out to be incorrect.
