x86_64-pokysdk-linux/environment-setup.d/qt5.sh issues in b2qt SDK

Today I started adding jobs to jenkins that build software components using the cross compilation toolchain from a baked B2Qt SDK for TX2.

At the beginning of the script I source . /opt/sdk/environment-setup-aarch64-poky-linux as I should.

Sourcing this file from PC terminal only only shows warnings. But jenkins check every shell instructions return value to detect is the build is successful.

export OE_QMAKE_CC=$CC
export OE_QMAKE_CXX=$CXX
export OE_QMAKE_LINK=$CXX

should be changed to 

export OE_QMAKE_CC="$CC"
export OE_QMAKE_CXX="$CXX"
export OE_QMAKE_LINK="$CXX"

otherwise build fail with error:

 
export OE_QMAKE_CC=aarch64-poky-linux-gcc --sysroot=/opt/sdk/sysroots/aarch64-poky-linux
/tmp/jenkins6449859542230643733.sh: 5: export: --sysroot: bad variable name
Also when executing that script these warnings show up:

...
+ qmake -query QT_INSTALL_LIBS Empty filename passed to function
...
+ qmake -query QT_INSTALL_HEADERS Empty filename passed to function
...
+ qmake -query QT_INSTALL_LIBS Empty filename passed to function
...
+ qmake -query QT_INSTALL_LIBS Empty filename passed to function
...

It turns out that QT_INSTALL_LIBS and QT_INSTALL_HEADERS are not defined. I'm not aware of the impact of these warning at this stage
