Subject: LRN: Add '-Wl,' prefix to -no-undefined
X-Git-Tag: initial-import-from-subversion-38251~16032
X-Git-Url: https://git.librecmc.org/?a=commitdiff_plain;h=b8fb774718de49d5a96e6cfa5b38a42b9f3f0e6a;p=oweals%2Fgnunet.git

LRN: Add '-Wl,' prefix to -no-undefined

-no-undefined is not a valid compiler option as of GCC 4.6.x
(it IS valid linker option).
Note that this REQUIRES an extra -no-undefined to be passed to
libtool (this is done by GN_LIB_LDLFAGS and GN_PLUGIN_LDFLAGS),
because libtool does not understand -Wl,-no-undefined.
