nasm: fix issue with repeat configure

This Fixes bug: [YOCTO #2176]

This fixes the following issue as mentioned in the bug:
If nasm-native has to be rebuilt (due to a signature change) it will fail:

| checking for a BSD-compatible install... /usr/bin/install -c
| /media/large/tmp/work/x86_64-linux/nasm-native-2.07-r1/nasm-2.07/configure:
line 4261: syntax error near unexpected token `-W'
| /media/large/tmp/work/x86_64-linux/nasm-native-2.07-r1/nasm-2.07/configure:
line 4261: `PA_ADD_CFLAGS(-W)'
| ERROR: oe_runconf failed
NOTE: package nasm-native-2.07-r1: task do_configure: Failed

The failure appears to be caused by do_patch_fixaclocal being run a second time

scripts/bitbake: try harder to check if pseudo exists

If pseudodone doesn't exist, we can get STAGING_BINDIR_NATIVE by calling
bitbake -e and use that as the path to check for pseudo before we give
up and try to build it explicitly first.

This is useful for people who share TMPDIR between multiple build
directories.

scripts/bitbake: allow switching between build directories

The recent addition of the check to ensure the user was in their build
directory disabled the ability to switch between build directories
without re-running the build environment setup script. We can rely
upon checking for conf/bblayers.conf instead, so use this check.

This does allow BUILDDIR (which is normally set by the environment
script) to be unset; however if it is set then it is assumed to be the
correct build directory and will be used in the error message that is
shown when we can't find conf/bblayers.conf.

scripts/bitbake: add/fix some comments

Add some comments explaining what this script does, fix one grammatical
error in a comment and make the tar-replacement-native comment give the
full reason why it is needed.

tune-cortexa8/9: fix PACKAGE tunes being all armv7at even for non-Thumb ones

All PACKAGE_EXTRA_ARCHS for cortexa8, cortexa8t and cortexa8-neon have typo in
referencing tune-armv7at even for non-Thumb modes. Probably a copy/paste error.
That's not the case for recently-added hard-fp tunes.

Same for cortexa9.

cross-canadian.bbclass: fix rpath for sdk executables

This makes the libraries located in places like this findable:
/usr/local/oecore-x86_64/sysroots/x86_64-oesdk-linux/usr/lib

Which avoids linking cross canadian sdk executables with host libraries like this:
