Nalin Dahyabhai |

Build binaries in this package as RELRO PIEs, libraries as partial RELRO,
|
|
Nalin Dahyabhai |
2202e37 |
and install shared libraries with the execute bit set on them. Prune out
|
|
Nalin Dahyabhai |
0fde11f |
the -L/usr/lib* and PIE flags where they might leak out and affect
|
|
Nalin Dahyabhai |
2202e37 |
apps which just want to link with the libraries. FIXME: needs to check and
|
|
Nalin Dahyabhai |
2202e37 |
not just assume that the compiler supports using these flags.
