1. Subtraction was performed on the current position
regardless of the success of the lseek operation.
In the event of an error, this resulted in the
current position being erroneously set to -2,
which bypassed the intended error handling
mechanism. The proposed change performs error
checking immediately following the lseek operation,
prior to any modification of the current position.
This ensures that a failed lseek operation will
correctly trigger the appropriate error handling.
2. The error checking logic was based on the assumption
that lseek would return `offset - 1` upon failure.
However, this is not consistent with the behaviour of
lseek as specified in the POSIX standard, which
stipulates that lseek shall return -1 in case of
an error. The code has been updated to reflect this
standard, improving reliability and compliance.

Off by default, build behaves normally.
WITH_META_MODE we get auto objdir creation, the ability to
start build from anywhere in the tree.
Still need to add real targets under targets/ to build packages.
