When ALSA is not installed on the users system, the error:

"Package alsa was not found in the pkg-config search path.
Perhaps you should add the directory containing `alsa.pc'
to the PKG_CONFIG_PATH environment variable
Package 'alsa', required by 'virtual:world', not found"


extra line?

is printed 3 times, which generates unnecessary noise.
Hence, Remove unnecessary noise using `--silence-errors` on LDLIBS
assignment, so the message is printed only once.

I would say this message is alerting the user that the package is missing.
Why would you want to delete it?

This can also be handled like this:
---
CHECK := $(shell pkg-config --exists alsa; echo $?)
ifneq ($(CHECK),0)
$(error Package alsa not found! Add directory containing alsa.pc in PKG_CONFIG_PATH)
endif
---


This is a better solution than suppressing errors.
