glibc FTBFS on Alpha with multiple testsuite failures on Alpha and has
been doing so for some time.  A number of these failures are fixed
by recent upstream glibc commits:

8e41f6008df3 alpha: add the denormal trap enable bit to FE_NOMASK_ENV
a32db99a38c5 alpha: expect test-float32x-float64-div to fail
c056561d31a2 fix setrlimit compat symbol for negative rlim values
4a07bb292f92 alpha: Fix stack alignment in makecontext

Other floating point failures are due to bugs in the kernel and fixes
for those have made it into the 7.3 kernel merge window and hopefully
will appear in a stable series kernel in the near future.

I attach a patch to update the expected testsuite failures for Alpha
in debian/testsuite-xfail-debian.mk

With the above upstream commits, the attached patch and building
under a patched kernel, glibc builds successfully on Alpha.

Cheers
Michael.
