+gdb/testsuite: fix FAILs in fileio.exp
+
+I'm experiencing intermittent FAILs in fileio.exp when running on (my)
+CI:
+
+    FAIL: gdb.base/fileio.exp: Open a file
+    FAIL: gdb.base/fileio.exp: Creating already existing file returns EEXIST
+    FAIL: gdb.base/fileio.exp: Open for write but no write permission returns EACCES
+    FAIL: gdb.base/fileio.exp: Writing to a file
+    ...
+
+The problem turned out to be the way the OUTDIR gets defined in fileio.c.
+The path is passed down "naked" and turned into string by STRINGIFY macro.
+
+However, if the path happens to contain name of unrelated pre-existing
+C macro, this macro gets expanded during the "stringification", resulting
+in (likely) different path than used in fileio.exp and therefore causing
+failures.
+
+For example, if the GDB is compiled and tested in directory
+
+    /var/lib/jenkins/workspace/binutils-gdb/build/x86_64-linux-gnu
+
+then fileio.c is compiled with
+
+   -DOUTDIR_=/var/lib/jenkins/workspace/binutils-gdb/build/x86_64-linux-gnu/gdb/testsuite/outputs/gdb.base/fileio
+
+But because there's also C macro named "linux" defined to 1, the resulting
+OUTDIR is actually:
+
+   /var/lib/jenkins/workspace/binutils-gdb/build/x86_64-1-gnu/gdb/testsuite/outputs/gdb.base/fileio
+
+This commit fixes this by defining the OUTDIR as string literal in first
+place (similarly to how it was done prior commit cc91060) and updating
+quote_for_host to handle strings that themselves contains quote (").
+
+Tested on x86_64-linux by running all tests using quote_for_host with
+both target board unix and host/target board local-remote-host-native.
