* libc/machine/i386/i386mach.h: added SOTYPE_FUNCTION to set type of global entry points if _I386MACH_NEED_SOTYPE_FUNCTION is defined; Added __CLI and __STI macros (controlled via _I386MACH_ALLOW_HW_INTERRUPTS macro). * libc/machine/i386/f_atan2.S libc/machine/i386/f_atan2f.S libc/machine/i386/f_frexp.S libc/machine/i386/f_frexpf.S libc/machine/i386/f_ldexp.S libc/machine/i386/f_ldexpf.S libc/machine/i386/f_log.S libc/machine/i386/f_log10.S libc/machine/i386/f_log10f.S libc/machine/i386/f_logf.S libc/machine/i386/f_tan.S libc/machine/i386/f_tanf.S libc/machine/i386/memchr.S libc/machine/i386/memcmp.S libc/machine/i386/memcpy.S libc/machine/i386/memmove.S libc/machine/i386/memset.S libc/machine/i386/setjmp.S libc/machine/i386/strchr.S libc/machine/i386/strlen.S: (that's libc/machine/i386/*.S) added SOTYPE_FUNCTION(symbol) for all global entry points. * libc/machine/i386/setjmp.S: removed code replicated in libc/machine/i386/i386mach.h and included i386mach.h instead; Use __CLI and __STI instead of cli and sti.
