grischka d2f8ceac7a tccrun: review last changes
- LIBTCCAPI int tcc_set_backtrace_func(void *ud, ...)
  accept opaque user data pointer,
- tcc -vv -run... : show section info
- use memalign() to allocate runtime memory
- printline_/dwarf : pass output to parent function
- tccpe.c : fix -nostdlib -run
- --config-backtrace=no : make it work again

Usage: configure [options]
Options: [defaults in brackets after descriptions]
Standard options:
--help print this message
--prefix=PREFIX install in PREFIX [$prefix]
--exec-prefix=EPREFIX install architecture-dependent files in EPREFIX
[same as prefix]
--bindir=DIR user executables in DIR [EPREFIX/bin]
--libdir=DIR object code libraries in DIR [EPREFIX/lib]
--tccdir=DIR installation directory [EPREFIX/lib/tcc]
--includedir=DIR C header files in DIR [PREFIX/include]

--infodir=DIR info documentation in DIR [SHAREDIR/info]
Advanced options (experts only):
--source-path=PATH path of source code [$source_path]
--sysroot=PREFIX prepend PREFIX to library/include paths [$sysroot]
--cc=CC use C compiler CC [$cc]
--ar=AR create archives using AR [$ar]
--extra-cflags= specify compiler flags [$CFLAGS]
--extra-ldflags= specify linker options [$LDFLAGS]
--debug include debug info with resulting binaries
--disable-static make libtcc.so instead of libtcc.a
--enable-static make libtcc.a instead of libtcc.dll (win32)
--disable-rpath disable use of -rpath with libtcc.so
--with-libgcc use libgcc_s.so.1 instead of libtcc1.a
--with-selinux use mmap for executable memory (tcc -run)
--enable-cross build cross compilers (see also 'make help')
--sysincludepaths=... specify system include paths, colon separated
--libpaths=... specify system library paths, colon separated
--crtprefix=... specify locations of crt?.o, colon separated
--elfinterp=... specify elf interpreter
--triplet=... specify system library/include directory triplet
--tcc-switches=... specify implicit switches passed to tcc
--config-uClibc,-musl enable system specific configurations
--config-mingw32 build on windows using msys, busybox, etc.
--config-backtrace=no disable stack backtraces (with -run or -bt)
--config-bcheck=no disable bounds checker (-b)
--config-predefs=no do not compile tccdefs.h, instead just include
--config-new_macho=no|yes Force apple object format (autodetect osx <= 10)
--config-codesign=no do not use codesign on apple to sign executables
--dwarf=x Use dwarf debug info instead of stabs (x=2..5)
Cross build options (experimental):
--cpu=CPU target CPU [$cpu]
--targetos=... target OS (Darwin,WIN32,Android/Termux) [$targetos]
--cross-prefix=PREFIX use PREFIX for compile tools [$cross_prefix]
