gdbserver >= 7.2 comes with an optional library to use tracepoints,
the In Process Agent (IPA) library, libinproctrace.so.
Say 'y' if you intend to use tracepoints when debugging your
programs with gdbserver.
Note: Currently, building this library is not possible when the
gdbserver is built statically. This is a limitation in
crosstool-NG, so do not bug upstream about it...
config GDB_NATIVE_STATIC
bool
prompt "Build a static gdb binaries"
depends on EXPERIMENTAL
help
In case you have trouble with dynamic loading of shared libraries,
you will find that a static gdb comes in handy.
However, it has been noticed at least on x86 that enabling this
option produces an invalid gdb binary. It is linked with
"-static -Wl,--dynamic-list=..." which
# (a) requests invalid program interpreter
# (b) crashes glibc/uClibc-ng and does not work with musl
# See https://sourceware.org/ml/libc-alpha/2017-03/msg00267.html
It is possible it would work with other architectures, hence it is
not completely removed. Use with care and report to the mailing list
if the resulting binaries work.

help
Say 'y' if you do not want gdbserver to require libstdc++.so on the
target.
