Robert Yang d6bc389e81 bitbake: bitbake: pysh: Improve error handling for shell code
The p_error() is used for printing errors when parse shell code, but it can't
the EOF error correctly

- Add the following lines to quilt.inc
  do_configure_prepend () {
      find ${s} -name "*.in" -exec sed -i -e "1s,^#\!.*@perl@ -w$,#\! @perl@\nuse warnings;," {} \;
      if [ hello ]; then
  }

- Before the patch:
  $ rm -fr cache/ tmp/cache/; bitbake -p
  [snip]
  WARNING: /path/to/quilt/quilt-native_0.65.bb: Error during finalise of /path/to/quilt/quilt-native_0.65.bb
  [snip]
  bb.pysh.sherrors.ShellSyntaxError: None
  followed by:

  We can see that this isn't easy to debug, let p_error() check wheter it is EOF
  and print appropriate errors can improve the error message. And don't let
  codeparser.py except pyshlex.NeedMore (in fact, it never worked since p_error()
  only raise ShellSyntaxError), but make it print the last 5 lines which might be
  useful for debuging.

- After the patch
  $ rm -fr cache/ tmp/cache/; bitbake -p
  [snip]
  ERROR: /path/to/quilt/quilt_0.65.bb: Error during parse shell code, the last 5 lines are:
      find /path/to/quilt/0.65-r0/quilt-0.65 -name "*.in" -exec sed -i -e "1s,^#\!.*@PERL@ -w$,#\! @PERL@\nuse warnings;," {} \;
      if [ hello ]; then
      autotools_do_configure
      sed -e 's,^COMPAT_SYMLINKS.*:=.*,COMPAT_SYMLINKS    :=,' -i /path/to/quilt/0.65-r0/quilt-0.65/Makefile

QEMU Emulation Targets
======================

To simplify development, the build system supports building images to
work with the QEMU emulator in system emulation mode. Several architectures
are currently supported in 32 and 64 bit variants:

  * ARM (qemuarm + qemuarm64)
  * x86 (qemux86 + qemux86-64)
  * PowerPC (qemuppc only)
  * MIPS (qemumips + qemumips64)

Use of the QEMU images is covered in the Yocto Project Reference Manual.
The appropriate MACHINE variable value corresponding to the target is given
in brackets.
