Bug#913946: llvm*-dbgsym still missing

[Rebecca N. Palmer]

Control: reopen -1

Still no -dbgsym packages, and the build log contains

dh_strip -p libomp5-7 --dbgsym-migration='libomp5-7-dbg (<< 
1:7~svn327768-1~)'
PATH=/<<BUILDDIR>>/llvm-toolchain-7-7.0.1~+rc3/:$PATH 
LD_LIBRARY_PATH=/<<BUILDDIR>>/llvm-toolchain-7-7.0.1~+rc3/debian/tmp//usr/lib/llvm-7/lib/ 
dh_strip -a -v -XlibFuzzer.a -Xlibc++.a -Xlibc++abi.a 
-Xlibc++experimental.a -XlibclangTidyModernizeModule.a
ERROR: ld.so: object 'libfakeroot-sysv.so' from LD_PRELOAD cannot be 
preloaded (cannot open shared object file): ignored.

which again looks like breaking fakeroot by replacing (rather than 
adding to) LD_LIBRARY_PATH.  (This time the package sizes are about 
normal, but at least libLLVM-7.so.1 has become executable again.)

I suspect the cause is
https://salsa.debian.org/pkg-llvm-team/llvm-toolchain/commit/d441237cacb871abfebec1353b4b64398a362b0b
(and if the commit log is what you intended, the test is the wrong way 
round).

If you still want to use llvm-strip I again suggest 
LD_LIBRARY_PATH=$$LD_LIBRARY_PATH:[build dir] and calling dh_fixperms 
again after dh_strip, but I thought the point of -fno-addrsig was to be 
able to use GNU strip.
