define BUILD_HELP_INFO
# Build code with verifying or not.
# target all is the "build" with verify.
# Args:
#   WHAT: binary names to build. support: $(BINARIES)
#         the build will produce executable files under ./$(OUT_BINPATH)
#         If not specified, "everything" will be built.
#
# Example:
#   make TARGET
#   make TARGET HELP=y
#   make TARGET WHAT=gm
#   make TARGET WHAT=lc GOLDFLAGS="" GOGCFLAGS="-N -l"
#     Note: Specify GOLDFLAGS as an empty string for building unstripped binaries, specify GOGCFLAGS
#     to "-N -l" to disable optimizations and inlining, this will be helpful when you want to
#     use the debugging tools like delve. When GOLDFLAGS is unspecified, it defaults to "-s -w" which strips
#     debug information, see https://golang.org/cmd/link for other flags.
