Build failure with coreutils 8.12

[Bernhard Rosenkraenzer]

On a box with coreutils 8.12 installed, Linaro Android fails to build:

javac -J-Xmx512M -target 1.5 -Xmaxerrs 9999999 -encoding ascii -bootclasspath out/target/common/obj/JAVA_LIBRARIES/core_intermediates/classes.jar -
encoding UTF-8 -g -extdirs "" -d out/target/common/obj/JAVA_LIBRARIES/core_intermediates/classes \@out/target/common/obj/JAVA_LIBRARIES/core_interm
ediates//java-source-list-uniq || ( rm -rf out/target/common/obj/JAVA_LIBRARIES/core_intermediates/classes ; exit 41 )
libcore/luni/src/main/java/java/security/CodeSource.java:33: cannot find symbol
symbol : class X509Certificate
location: package java.security.cert
import java.security.cert.X509Certificate;
                         ^

Looking into this a bit, the problem seems to be with coreutils 8.12.
java-source-list-uniq (input file) is indeed missing an entry for java/security/cert/X509Certificate.java

java-source-list (from which it is generated) looks right.

java-source-list-uniq is built from java-source-list in build/core/definitions.mk, lines 1827 and following.

Looking at what's going wrong there shows what looks like we're triggering a coreutils bug:

Changing the "sort -u" to "sort | uniq" produces the expected results, so that may be an ok workaround

[Bernhard Rosenkraenzer (berolinux)]

Also affects coreutils 8.14

[Bernhard Rosenkraenzer (berolinux)]

Another possible (and better) workaround is to make sure "sort -u" is called in the C locale -- that works around the bug, and also fixes odd locales where 2 filenames actually might be interpreted as the same.

[Bernhard Rosenkraenzer (berolinux)]

Will submit a LANG=C patch once my test build has completed

Fix available in release 11.10 Linaro Android.
