Bug 1303766

It appears libasan and libubsan are missing after installing gcc and gcc-c++.

g++ -o cryptest.exe -DDEBUG -g2 -O1 -std=c++03  -Wno-deprecated-declarations -fPIC -march=native -pipe -fsanitize=address -fno-omit-frame-pointer bench.o bench2.o test.o validat1.o validat2.o validat3.o adhoc.o datatest.o regtest.o fipsalgt.o dlltest.o ./libcryptopp.a -pthread 
/bin/ld: cannot find /usr/lib64/libasan.so.2.0.0
collect2: error: ld returned 1 exit status
make: *** [cryptest.exe] Error 1

And:

g++ -o cryptest.exe -DNDEBUG -g2 -O2 -std=c++11  -Wno-deprecated-declarations -fPIC -march=native -pipe -fsanitize=undefined -DCRYPTOPP_NO_UNALIGNED_DATA_ACCESS bench.o bench2.o test.o validat1.o validat2.o validat3.o adhoc.o datatest.o regtest.o fipsalgt.o dlltest.o ./libcryptopp.a -pthread 
/bin/ld: cannot find /usr/lib64/libubsan.so.0.0.0
collect2: error: ld returned 1 exit status
make: *** [cryptest.exe] Error 1

It seems GCC unconditionally advertises Asan and UBsan support, even if the binaries are not installed. For example, here is our test to determine if we should perform the actual Asan and UBsan test runs. Both of the tests returned success.

# Set to 0 if you don't have UBsan
$CXX -x c++ -fsanitize=undefined adhoc.cpp.proto -c -o $TMP/adhoc > /dev/null 2>&1
if [ "$?" -eq "0" ] && [ "$IS_X86" -ne "0" ]; then
	HAVE_UBSAN=1
else
	HAVE_UBSAN=0
fi

# Set to 0 if you don't have Asan
$CXX -x c++ -fsanitize=address adhoc.cpp.proto -c -o $TMP/adhoc > /dev/null 2>&1
if [ "$?" -eq "0" ] && [ "$IS_X86" -ne "0" ]; then
	HAVE_ASAN=1
else
	HAVE_ASAN=0
fi

The fix is simple, but it makes me wonder why they are not installed in the first place.
