libpayload: Use a static copy of `font_glyph_filled()`
libpayload needs a static copy of the out of line function `font_glyph_filled()` in every TU that needs it. So make it static inline. This fixes a build error by gcc (Debian 7.1.0-12) 7.1.0 from Debian Sid/unstable. This happens with any libpayload based payload like coreinfo, nvramcui or tint. ``` […] LPCC build/coreinfo.elf (LINK) /src/coreboot/payloads/coreinfo/build/libpayload/bin/../lib/libpayload.a(corebootfb.libc.o): In function `corebootfb_putchar': /src/coreboot/payloads/libpayload/drivers/video/corebootfb.c:173: undefined reference to `font_glyph_filled' […] ``` Change-Id: I931f0f17b33abafdc49aa755a0dad65e28820750 Signed-off-by: Paul Menzel <pmenzel@molgen.mpg.de> Reviewed-on: https://review.coreboot.org/20897 Tested-by: build bot (Jenkins) <no-reply@coreboot.org> Reviewed-by: Nico Huber <nico.h@gmx.de> Reviewed-by: Patrick Georgi <pgeorgi@google.com>
