This is not expanded in a .PHONY target. It removes the functionality and completion of this target. It should not be changed.

The current version of the Makefile is not working for me for the fixture targets. The sample-app targets are not executed.
make sample-app/nethttp
make: Nothing to be done for `sample-app/nethttp'.This change fixed that, I'm not sure why.

Resolves #1637 and improves our support for stripped binaries.
.gosymtabsection is not required to parse the pcln table as stated in https://pkg.go.dev/debug/gosym#NewTableruntime.textsymbol from the instrumented binary. For binaries not including C code, this is the same as the start of the.textsection. However for those that use C code, this value will differ. This caused incorrect offsets to get probed when instrumenting a stripped binary that uses a CGO lib. An example of this is our DB example and test which uses the go-sqlite3 library.
