+# The `xerbla.o` file contains an absolute path in `xerbla.f.o`, but the options
+# `-fdebug-prefix-map` and `-ffile-prefix-map` cannot be used because gfortran does not support them.
+# To address this issue, we manually replace the absolute path with a relative path
+# in the generated `build.make` file.
+#
+# An issue has been reported: https://github.com/Reference-LAPACK/lapack/issues/1087,
+# requesting a fix in the source code.
+#
+# This workaround resolves the TMPDIR [buildpaths] issue by converting the absolute path
+# of `xerbla.f` to a relative path. The steps are as follows:
+#
+# 1. Locate all `build.make` files after the `do_configure` step is completed.
+# 2. Compute the relative path for `xerbla.f` based on the current build directory.
+# 3. Replace the absolute path with the calculated relative path in the `build.make` files
+#
+# Additionally, when ptests are enabled, apply a simpler workaround for ptest code:
+# - Replace occurrences of `${WORKDIR}` in all `build.make` files under the TESTING directory, excluding
+#   the MATGEN subdirectory, with a relative path prefix of `"../../.."`.
