OMG sorry for noise, yes there is still problem when missing thumb and
arm builds for the same machine with different PKGARCH and
eglibc-initial still fails

and the problem is basically that STAGING_BINDIR_TOOLCHAIN points to
different directory when building recipe with thumb enabled and
disabled, in this case gcc was built with thumb enabled and is installed
in:
sysroots/x86_64-linux/usr/bin/armv5te-oe-linux-gnueabi
OE qemuarm@ ~/build/oe-core $ ls
/OE/build/oe-core/tmp-eglibc/sysroots/x86_64-linux/usr/bin/armv5te-oe-linux-gnueabi
arm-oe-linux-gnueabi-addr2line arm-oe-linux-gnueabi-elfedit

arm-oe-linux-gnueabi-c++filt arm-oe-linux-gnueabi-ld.bfd
arm-oe-linux-gnueabi-ranlib arm-oe-linux-gnueabi-strip
but when building eglibc-initial with thumb disalbed, TUNE_PKGARCH
becames armv5e and STAGING_BINDIR_TOOLCHAIN in PATH points to wrong dir:
# $STAGING_BINDIR_TOOLCHAIN
# set conf/bitbake.conf:354
#
"${STAGING_DIR_NATIVE}${bindir_native}/${TUNE_PKGARCH}${TARGET_VENDOR}-${TARGET_OS}"
STAGING_BINDIR_TOOLCHAIN="/OE/build/oe-core/tmp-eglibc/sysroots/x86_64-linux/usr/bin/armv5e-oe-linux-gnueabi"
OE qemuarm@ ~/build/oe-core $ ls
/OE/build/oe-core/tmp-eglibc/sysroots/x86_64-linux/usr/bin/armv5e-oe-linux-gnueabi
ls: cannot access
/OE/build/oe-core/tmp-eglibc/sysroots/x86_64-linux/usr/bin/armv5e-oe-linux-gnueabi:
No such file or directory
Any idea how to resolve this correctly?
