Subject: build-sys: add SUID_LDFLAGS
X-Git-Url: https://err.no/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=3f3c9c909a41611ac5d2a9c151290296aa30a97f;p=util-linux

build-sys: add SUID_LDFLAGS

Programs which are usually installed with the setuid bit do need their own
CFLAGS and LDFLAGS.  SUID_LDFLAGS is analogic to SUID_CFLAGS.

       Notes:
-            * use SUID_CFLAGS when you want to define special compiler options
+            * use SUID_CFLAGS and SUID_LDFLAGS when you want to define special compiler options
               for typical suid programs, for example:
 
-                  SUID_CFLAGS="-fpic" ./configure
+                  SUID_CFLAGS="-fpie" SUID_LDFLAGS="-pie" ./configure
 
               Now this feature is supported for chfn, chsh, newgrp, write,
               mount and umount.
