Subject: [PATCH 1/1] package/uftrace: new package

Hello, first time trying to package something for BuildRoot and
sending a patch via email.

The package is a tracing utility similar to ltrace and strace that
allows profiling of programs and their library calls.

I have performed a run of ./utils/check-package package/uftrace/* with
the following result:

> 78 lines processed
> 0 warnings generated

I have performed a run of ./utils/test-pkg -d ../test-pkg -c
../uftrace.config -p uftrace -a

> 45 builds, 36 skipped, 0 build failed, 0 legal-info failed

The only architectures supported upstream are aarch64, arm and x86_64/i386.
I could not build the program without glibc so it's marked as
requiring a glibc toolchain.

I am looking for some pointers on how to upstream my modification and
feedback on the patch in its current state.
