In buildroot, stripping for the target is configured and implemented with the global `BR2_STRIP_strip` option that drive the stripping in the target-finalize step. So, we explicitly disable stripping at build time for the target variants. For the host variants, however, we don't much care about symbols and stuff, but smaller executables will hopefully load faster than bigger ones (disputable, given that sections in ELF files are paged-in on-demand), so we explictly enable stripping.

# Meson package infrastructure
|
|
#
|
|
# This file implements an infrastructure that eases development of
|
|
# package .mk files for Meson packages. It should be used for all
|
|
# packages that use Meson as their build system.
|
|
#
|
|
# See the Buildroot documentation for details on the usage of this
|
|
# infrastructure
|
|
#
|
|
# In terms of implementation, this Meson infrastructure requires
|
|
# the .mk file to only specify metadata information about the
|
|
# package: name, version, download URL, etc.
|
|
#
|
|
# We still allow the package .mk file to override what the different
|
|
# steps are doing, if needed. For example, if <PKG>_BUILD_CMDS is
|
|
# already defined, it is used as the list of commands to perform to
|
|
# build the package, instead of the default Meson behaviour. The
|
|
# package can also define some post operation hooks.
|
|
#
