[Lapack] bug in dsyevr.f when N = 1

[Julien Langou]

Dear Ashutosh,

for information I have just pushed your fix in our svn repository (well 
committed I should say then) so that we won't forget them at the next 
release.

Information is available at http://www.netlib.org/lapack/Errata/ under 
bug0044 and bug0045.

Best wishes, 
Julien.
