* bmp2rb generated a .h file that rockbox .c files used. * .h files in .c files were used to generate dependency graphs for make * When Make saw the .h file for the bitmap, it didn't know how what to do with them * Only arose in parallel builds Fixed this by adding explicit dependencies for the .h files as part of the existing 'bmpdepfile' function. Solves the Xduoo X3 bootloader build failure that I could trigger 100% of the time by using 'make -j8' Change-Id: I6b3e78dde26c820a3b6c7c286e7d6c981b8e01fc
