Another old man's memory agrees with Jim: I thought the 
result is in Godement's book on `faisceaux'; see also 
Swan's `Theory of sheaves'.

The problem may be to interpret it. A Gysin sequence is unlikely?

The Annals of Math Study 46 (Princeton 1960):

   Seminar on transformation groups, ed A. Borel et al,

is an interesting trip down memory lane, full of
forgotten technology like cohomology with weird
families of supports, the spectral sequence of Istvan
Fary, & similar now almost incomprehensible arcana...
