[gnutls-devel] gnutls.pc includes invalid flags

[Andreas Metzler]

Hello,

this is https://bugs.debian.org/857943 reported by Aaron M. Ucko:

----------------
he output of `pkg-config gnutls --libs --static` includes a flag of
the form -R/usr/lib/$DEB_HOST_MULTIARCH, which is not only superfluous
but also outright broken without a leading -Wl,:

$ gcc `pkg-config gnutls --libs --static`
gcc: error: unrecognized command line option ‘-R’; did you mean ‘-R’?
$ pkg-config gnutls --libs --static
-lgnutls -lz -R/usr/lib/x86_64-linux-gnu     -lp11-kit   -lgmp -lnettle -lhogweed -lgmp -lnettle -ltasn1 -lidn -lp11-kit -lz
----------------

Attached patch works for me.

(I am not totally sure whether it is useful to carter for incomplete
pkg-config setups at all. If there is no zlib.pc, the user will probably
not install gnutls.pc either.)

cu Andreas
