This is for Klemen Vodopivec the author of `PyDevice`
1) thanks for making this
2) I'm having some issues getting a simple ioc to build with pydev support
I'm using a Raspberry Pi and linux-arm as the host architecture
for specific reasons: using EPICS base 3.15.6, python 3.8.10 on ubuntu for arm64 in a docker container
The module itself builds alright. and the testing ioc runs just fine
When I create a basic IOC, with makeBaseApp.pl using the ioc template,
adding the lines as indicated:
```
analogCtrlIOC_DBD += pydev.dbd
analogCtrlIOC_LIBS += pydev
SYS_PROD_LIBS += $(shell $(PYTHON_CONFIG) --ldflags --embed | sed 's/-[^l][^ ]*//g' | sed 's/-l//g')
with the RELEASE file for the IOC pointed at the location of the support module
with `make` i get
```

PYTHON_CONFIG is set for python3
any thoughts?
