| 11 | # specify the program used to strip binaries. This is especially

| 12 | # annoying in cross-compiling environments, where the build's strip
|
|---|
| 13 | # is unlikely to handle the host's binaries.
|

| 14 | # Fortunately install-sh will honor a STRIPPROG variable, so we
|
|---|
| 15 | # always use install-sh in `make install-strip', and initialize
|
|---|
| 16 | # STRIPPROG with the value of the STRIP variable (set by the user).
